Abstract—The phase composition of titanium anode electrocatalytic coats based on cobalt, manganese, and nickel
oxides was analyzed by separating and interpreting an amorphous diffractogram component. A correlation was
conﬁ rmed between the data of the X-ray phase analysis of titanium anodes with an electrocatalytic coat based
on cobalt, manganese, and nickel oxides and the results of the simulation of probable oxide phases in analogous
coats obtained earlier on the basis of the spectral analysis experimental data.
Obtaining of base metals oxide systems is of interest
in connection with a possibility of their use as electrode
materials for certain electrochemical processes [1–6]. In
particular, cobalt oxide is rather promising for the process-
es of oxygen reduction  and of electrolysis of chloride
solutions [1–3]. In comparison with oxides of other base
anodes possess a rather low overvoltage of
chlorine liberation, a high selectivity toward discharge of
chloride ions, and a satisfactory rust resistance.
However anodes prepared only from Co
in competition with electrode materials based on ruthe-
nium and titanium oxides, as they rank below them in the
basic characteristics speciﬁ ed above, except for selectivity
in relation to a chloric reaction . It is likely that mul-
tiphase systems from oxides with structures of different
structural types can be highly effective metal-oxide elec-
trodes. Their electrophysical and electrocatalytic proper-
ties in many respects are deﬁ ned both by characteristics
of phase and structural disordering and by a number of
phases and corresponding interphase boundaries, extent
and character of a deviation of phase compositions from
a stoichiometry, and the presence of structural defects.
The data on the elemental composition of surface lay-
ers of metal oxide titanium anodes based on mixed oxides
of base metals electrodeposited from aqueous solutions
of their salts upon polarization by asymmetric alternating
current and the results obtained earlier  have allowed
us to analyze a probable phase composition of these
layers. The further development of the studies  is the
nondestructive X-ray study of the phase composition of
the titanium anode with an electrocatalytic coat based on
cobalt, manganese, and nickel oxides.
The diffractogram of a metal oxide electrode with
the coat of metal oxides electrodeposited from aqueous
solutions of their salts should contain crystalline and
amorphous components. These components of a diffrac-
tion pattern carry information on the composition and
structure of a metal carrier and main crystalline oxide
phases of a coat, on the composition of highly dispersed
formations, and also on the short-range order of probable
amorphous phases entering into the composition of the
electrocatalytic coat .
The aim of the present work was to determine by the
X-ray diffraction technique the phase composition of
the titanium anode electrocatalytic coat based on cobalt,
manganese, and nickel oxides electrodeposited from
aqueous solutions of their salts.
The experiments were carried out with four samples in
the form of plates of WT 1-0 grade titanium with an area
