Abstract—The methods of the coprecipitation of chitosan and copper-containing particles on a carbon ﬁ ber used
as a cathode and also of the precipitation of copper(II) on a carbon-ﬁ ber electrode preliminarily modiﬁ ed by chi-
tosan were studied for feasibility of obtaining composites containing copper oxide/copper in a chitosan matrix.
The composition, morphology, structure of the organic-mineral composites were studied by the methods of X-ray
phase analysis, scanning electronic microscopy, X-ray photoelectron spectroscopy, and ESR spectroscopy.
At present electrodeposition of metal oxides and hy-
droxides is being developed intensively. A great number
of oxides, both mixed and individual including copper
oxides, are obtained with the use of electrochemical
Among numerous oxides of transition metals, copper
oxides are of interest in due to their wide practical use.
The cupric oxide CuO is applied as a basis for obtaining
high-temperature superconductors and materials with
giant magnetoresistance; Cu
O is used in solar elements,
electronics, magnetic memory units, and gas sensors .
Catalysts based on copper, its oxides and complexes are
used in various chemical processes [3, 4]. Both copper(I)
oxide itself  and materials modiﬁ ed by it, for example
chitosan  or carbon nanotubes , are of interest as
photocatalysts. Materials modiﬁ ed by copper nanopar-
ticles possess antibacterial properties .
Highly dispersed cuprous oxide powders can be ob-
tained with the use of electrochemical techniques [5, 9].
The cuprous oxide Cu
O can be deposited on various
carriers (chitosan [6, 10], carbon nanotubes ) or can
be precipitated as thin ﬁ lms on conducting substrates
[11–13]. In the ﬁ rst two cases Cu
O is obtained by
anode dissolution of copper plates, and to obtain ﬁ lms,
O is precipitated on a metal cathode. Deposition of
nanoparticles of copper(I) oxide on a substrate is caused
by the necessity to stabilize obtained particles, as Cu
nanoparticles are readily agglomerated [7, 10]. As known,
the application of polymers is rather effective for raising
stability of metal-containing nanoparticles . Recently
the attention is being paid to a new class of composites
containing inorganic nanoparticles in polyelectrolyte
matrixes . In particular, the method of cathode elec-
trophoretic deposition of cationic polyelectrolyte chitosan
with simultaneous electrosynthesis of inorganic nanopar-
ticles of oxides and metals was used for the formation
inorganic nanoparticles in a polymeric matrix . Appli-
cation of the biocompatible polymer chitosan is attractive
due to the opportunity of ﬁ xing highly dispersed Cu
Furthermore, chitosan is capable to play
a role of a sorbent for removing copper(II) ions formed
in the course of degradation of pollutants, if Cu
O is used
as a photocatalyst .
Among other methods most often used for the prepara-
tion of nanoparticles, electrochemical synthesis has some
advantages as it is a low-temperature method, is rather
simple in implementation, and is characterized by a pos-
sibility to control parameters deﬁ ning the composition of
synthesized products. According to published data, when
