TITLE: Kinetics of the Isotopic Exchange Between Molecular Oxygen
and Oxygen at the Surfaces of Iron, Cobalt, Nickel, and
Copper Oxides
PERIODICAL: Kinetika i kataliz, 1960, Vol. 1, No. 4, pp. 566-575
TEXT: The kinetics of the isotopic exchange between molecular oxygen and
oxygen at the surfaces of iron, cobalt, nickel, and copper oxides were
Investigated. The measurements were made statically by using the continuous-
flow apparatus shown schematically in Fig. 1. Oxygen containing an excess
is is
of 0 was prepared by electrolysis of water containing 4 at% 0 . The
specific surfaces of the oxide catalysts were determined by the BET method.
The following values were found: Co 3 04: 7-7 m 2/g ; Fe203: 27.2 m 2/g;
NiO: 7-8 m 2/g; Cuo: 17.6 m 2/g The exchange of oxygen between molecular
oxygen and solid oxides at 10 30 mm Hg and 100 - 4000C is a complex

process. The Fe 203 surface is homogeneous with respect to the exchange
reaction, while the surfaces of Cc 3042 NiO and CuO are inhomogeneous in
this respect. The isotopic exchange :,f' oxygen with Fe 2057 NiO, and CuO
is illustrated in Table 1. A graphic representation -)f isotopic exchange
as a function of time is given in Figs. 2-5. The kinetics of the exchange
between gaseous oxygen and oxygen at the surface of Cc 304v NiO, and CuO
cannot be described by an equation of first order. Herefrom, the authors
conclude that the surfaces of these catalysts are inhomogeneous. The
isotopic exchange with Fe 203$ however, fits an equation of first order.
Fig. 6 shows log() F) as a function of the time of exchange in the case
of Fe 203' F = (C0 C)/(C - C 00 ), where Co ~ concentration of 018 on the
surface of the lattice, 0 - concentration of 0 is in the gas, Cm = con-
centration of 0 18 on the surface of the lattice at equilibrium. Fig. 7
shows the changes in the activation energy of isotopic exchange along the

surface. The reactivity of the oxides with respect to isotopic exchange
changes in the same degree as their catalytic activity in hydrogen
oxidation, i.e. RCo304 > RNiO > RGUO ~ RFe 203~ BV20 5* The rates of
isotopic exchange and hydrogen oxidation are functions of the concentration
of the oxygen adsorbed at the catalyst surfaces. S. M. Karpachev,
A. M. Rozen and S. Z. Roginskiy are mentioned. There are 7 figures, 2
tables, and 14 references: 10 Soviet, 4 British, and 1 Japanese.

TITLE: Chemical composition and catalytic properties of silicon-
zirconium catalysts
PERIODICAL: Kinetika i kataliz, v. 2, no. 1, 1961, 84-93
TEXT: Basin,-, on the fact that the catalytic properties of oxide mixtures
are not additive, the present work studies the chemical nature and
catalytic properties of silicon-zirconium catalystet ind whether this
deviation from additivity is due to different accel:.--ation of the
individual reactions by the components (a view,hele ` e.g., by B. B.
Corson, et al., Ref. 1, see below), or to the chr ical nature of the
catalyst being changed by interaction between the cwo components. The
following catalysts were prepared: (1) Silica gel by hydrolysis of the
ethyl ester of orthosilicic acid, and ignition of the precipitate at
500OC; (2) Zro2 by precipitation of ZrOCI2with NH 39 and ignition of the
precipitate at 5000C; (3) mixed catalysts by joint precipitation of ZrOCl2

and the ortbosilicic acid ester with NH 3 from aqueous-alcoholic solution,
hydrolysis of the precipitate, and ignition; component ratios of the
mixture and temperature of ignition were varied; (4) mechanical mixtures
of the two components. The structure of the Si-Zr catalysts was examined
by (A) X-ray analysis. Results obtained were: (a) ZrO 2 crystallizes
at 400-4500%', in the tetragonal variety which at 5000C passes over to the
monoclinic variety; (b) silica gel ignited at 10000C is amorphous;
(c) jointly precipitated Si-Zr mixtures containing up to 15% Si02 after
ignition at 5000C exhibited the structure of a solid solution which
decomposed after ignition at 10000C and was re-formed when the temperature
dropped below 10000C. (B) Infrared spectrometric analysis in an V.
