ABSTRACT: Experimental material concerning the cathodic reduction of
ozone on the rotating platinum electrode in sulfuric acid
solutions at 25, 0. -30, -50 and -700C was the basis for
thorough investi.gations on the mechanism of the electrode
reaction in the region of high anode potentials (analogous
to the experiments in reference 3). The apparatus used was
previously described (Ref 4). The rate of rotation of the
platinum electrode was about 3000 rpm in all experiments.
The stationary potential was determined as a function of the
temperature at constant ozone concentration in,10 nH

for the ozone reduction (Fi.-s 3,4), which is explained in
terms of a two-stage reduction reaction (0 3+ e 03;

TEXT: The application of semiconductor materials as heterogeneous
sensitizers in the transformation of radiation energy into chemical energy
is of special importance for the utilization of nuclear radiation to
initiate radiation-chemical reactions. in continuation of previous in-
vestigations, the results are given of the photo- and radiation-chemical
decomposition of concentrated H202 solutions with suspended Fe20,. A
nPK -2 (PRK-2) quartz lamp served as light source, while Co60 with an
activity of 81) Curies was used as I-radiation source; the experiments were
carried out in an apparatus warranting a stabilization of temperature,
good mixing of the solution, and regular irradiation. The experimental

results obtainel show that the catalytic effect of Fe20 3 upon the H202
decomposition due to light irradiation, as well as the V-rays is strongly
increased. This means that a chain reaction sets in on the surface of Fe 203
which is due to an energy transfer causing an excitation of the particles
of the Fe 203surface, and that the chain reaction of the H202 decomposi:-
tion is passed on into the liquid, The high photo- and radiation-chemical
activity of Felo can only be lue to the effect of a heterogeneous

sensitization 'which depends on the electronic state of the semiconductor)
The active centers on the Fe2c3 surface which cause the chain reaction
are the same in the thermal H202 decomposition and in the decomposition
due to radiation. A temperature increase accelerates in both cases the rate
of decomposition. Since no particular difference was observed between
the effect of the ultraviolet light and the I-radiation, the reaction
mechanism is assumed to be the same in both cases. Apparently, the higher
energy (approximately 1.25 Mev) of the y-quanta is transformed into a

TEXT: In eazlier papers (Eefs. 1-4) the authors found that the potential
of a Pt electrode in irradiated 0.8 N H 2so4 (irradiation dose
2.1015 ev/OJ.s'eo) assumes a value close to that of the potential of the
9 eleetrods. The present papef6 deals yith the results obtained by a more
intensive irradiation (6.1.10 ev/oM-'.seo)o The experiments were carried
out with a Cj)60 radiation source,* and the method is described in Refs. 2
and 3. Fig. I shows the dependence of the potential of the Pt electrode
in oxygen-free 0.6 N H280 4 on the duration of irradiation. Also with this
intensityo selectivity of the Pt electrode with respect to the reduaing
radialytio products was observed. The potential assumes a value of between

then rises up to 0.85 v (Fig. 1). For the oxidation of the reducing
radiolytic products and the reduction of the oxidizing radiolytic
productog occurring in the irradiated solutiong the authors derive

gaseous phase -the stoiohlDmetria ratio between the reducing and the
oxidizing products is, however, disturbed, which leads to a positive
shifting of the potential in the case of high doses. Fig. 2 shows the
dependence of the depolarization current at 0-4 v on the duration of
irradiation. The course of this curve is,explained as follows: Due to
the selootivity of the Pt electrode, the oxidation of H at first pre-
dominates. Aa a result of the escape of R into the gaseous phase, the
reduction of R 202 is accelerated, the total current (I R - IR 0 ) decreases

to form and no bldrogen can escape, a potential of +20 mv quickly forms,
which remains constant throughout the experiment (20 h)(Fig- 3)~ Because
of the increasing concentration of the oxidizing products, the polariza-
tion current quickly decreases (Fig- 4). The ionization of the H on the
Pt electrode, which is formed by radiolysis, may therefore be carried out
in the *&as of a steady potential only if the reduction of the cxidizing
products taken place at the same rate (e,g., on a second electrode which
is selective for these products). At the same time, a current will flow
through the outer circuit. There are 4 figures and 7 references- 6 Soviet

polarization and durve 5 for not previously polarized p-type germanium.
The inflection of the polarization curves of p-type germanium at high
amperages is explained by the inhibition of electron diffusion, which
does not occur vith n-type Go, because the latter has a high electron con-
centration in the conduction band. Fig. 2 a shows the change with time in
the overvoltage-I after switching on 10 ma/cm 2. The occurring maximum of
'I depends on the pretreatment of the electrode. In germanium coated with
a thick oxide layer (1000 - 2000 A), no maximum ofiZ occurs. The drop of
the I-ourve after the maximum is explained by an increase in the rate of
the generation of electrons on the germanium surface, which is caused by
the absorption.of hydrogen. During illumination of p-type Ge a rapid
drop ofiZ occurs due to a photoeffect. Besides, it was observed that in
the presence ol'7 hydrogen this drop occurred already in the region of
diffusion inhibition, which is explained by photodesorption of H. Fig. 3

source during illumination and in the dark. In the case of p-type Ge the

photoeffect vanishes after a short cathodic polarizationg and in n-type
Ge it is intensified. Short anodic polarization no longer reduces the
potential to the initial value. The authors draw the conclusion that the
adsorption of hydrogen on the germanium surface increases its negative
charge aue to the formation of acceptor levels in the forbidden band.
Molecular hydrogen does not produce this effect. The illumination of
polarized p-type Ge influences the rate of gas separation in an alkaline
solution (Fig. 4). Photodesorption occurst Under the action of light the
adsorbed hydrogen dissolves in the electrolyte. There are thereforetwo
steady states: a dark state and a light state, where the latter differs
from the former by the lower probability of gas-bubble formation and the
higher content of dissolved hydrogen in the electrolyte% There are

pp. 889 - 89a
TEXT: It was the aim of the authors to investigate the effect of
illumination upon the structure of the interface between germanium and
electrolyte as well as upon the anodic dissolution of germanium. The
method employed. permitted illumination of the electrodes through the
solution as well as of the dry side of the electrodes. (The electrode
formed the bottom of a cylindrical Teflon vessel.) The experiments were
carried out with monocrystalline n-type germanium of different resistivi-
ties in 0.1 N XaOH in a nitrogen atmosphere. The Ge electrodes were
etched with CP-4 (SR-4). Illumination was carried out by means of an
incandescent lamp within the range of 0.4 - 0.7,,w, partly with a constant
current, and partly with constant voltage, It follows from Fig. 1 that

the system was aensitive to light within the entire region of polariza-
tion. The potential barrier Is removed by illumination, and the poten-
tial drops within the saturation region to the constant value of 0.5 v.
Above the breakdown potential this effect stops. In the initial part of
the polarization curve, the rate of the anodic reaction is not limited
by the concentration of minQrity carriers (Fig. 2). The last-mentioned
author derived equation (1);: 1 = k 9xp(-,&yF/RT).9xp(--aAHF/RT) for this
region in an earlier paper (Ref. 7); here,,Ay denotes the potential

electrons and holes must therefore also influence and the total

respectively. Visible light and gamma rays apparently give rise to
similar excitation processes in the semiconductor, with the absolute values
of I&Vc under gamma irradiation being higher than with visible light.
Fig. Z.,shows the typical dependence of potential change on the duration of
irradiation for an initial potential of 0.200 v. Fox the other initial
potentials examined) the curve shape wan similar, but the absolute values
of A_Vc were lower. The potential jump at the beginning and the following
slow approach of the potential to the steady state are due to the excita-
tion of the semiconductor and to the electrochemical oxidation,
respectively. The compon&nts (OHI 02) appearing in the radiolysis of
water speed up the electrochemical reaction. The experimental results
available so far are not sufficient to back the assumption of a specific
mechanism for the radio-electrochemioal process on the CU*CU20 electrode.
They suffice, however, for the following hypothesis: Due to the action of
radiationp Clu.20 can be oxidized to Cu(OH)2 . hydrogen peroxide may also
be produced Isy a sensitized reaction involving the oxygen which is always
present in C112P. The radio-electrochemical process on the Cu-Cu20
electrode is of interest also for heterogeneous radiation sensitizztion.

A noticeable sensitization,.however, is only possible in the case of a
sufficiently large acting surface of the sensitizer. According to data
available on the dampi-A'g of luminescence (see also Veselovskiy V. I.,

1958), the energy bf excitation of a semiconductor by electrons can.be
transferred to the solution componente. A participation of excit4d
electrona of the semiconductor with more than 3.0 ev in the reaction, and
an excitation of radio-chemical processen by the energy absorbed and
converted by the semiconductor are possible. The rate of disintegration
under the action of irradiation is considerably increased by the presence
of an Fe 203suspension. In a microheterogeneous system, the suspension
Fe203-H 202solution is not substantially changed by radiation, and,
therefore, tho rate of hydrogen peroxide decomposition does not change
either. The heterogeneous process depends on the electron state of the
semiconductor, and the active surface centers determining the reaction are
of ihe same nature during decomposition due to heat and irradiation. The

chemical processes is described. The process of changing the elec-
trode potentials was carried out in aqueoas H 280 , under the action
of r rays, using gold and platinum electrodes. He Pt electrode po-
t6ntial drops from about 0.9 v to.0.05. v '(stationary potential) af-
ter 30 hours and that of the Au electrode increases slowly from
about 0.7 v to 0.9 v (stationary potential). The fall of the Ft
electrode potential to a value near that of the hydrogen electrode
-is explained by the selectivity of the Pt electrode in respect to
the radiolysis products of water (H and H2). stationary potentials

Investigations on, tile relationuhip between the decomposition of ,

.no marked discrepancies in the yield of 11 202 could be recorded in
the presence or absence of ihe suspension (2,4 and 2.2 respective-

that the 00 2 is absorbed by,the solution, increasing its pH. This
increase could also be observed during irradiation for e.g. 5 hours.
Decompo6ition yields were much higher when the experiments were
carried out in a current of nitrogen; increased reaction rates were

TEXT: The dependence of the potential, photoeffect, and capacitance on the

The anodic polarization curves showed maxinium saturation current at the
lowest H202 concentration. These data suEgest that the etching of
,germanium in alkaline hydrogen peroxide solutions proceeds via a stage of
GeO formation, and is ttlectrochomical in nature, since H 202 is reduced on
the cathode and Ge is dicsolved on the anode. With a high H 202 excess,
however, GeO oxidizes to GeO,, and the dissolution process is inhibited.
