Electrocatalysts for methanol oxidation was studied. They were prepared on the base of carbon nanotubes, covered by polyelectrolytes with differently charged functional groups, which was changed by platinum with subsequent reduction. Then ruthenium was spontaneous deposited on metal platinum. The prepared catalysts were more active compared to commertial ETEK Pt-Ru (50:50 at. %) catalysts.

The influence of partial substitution of Zr⁴⁺ ions for Ge⁴⁺ ions at high conduction solid electrolyte Li_3.75Ge_0.75V_0.25O₄ was investigated. It was established that introduction of zirconium ions leads to noticable increasing of electrolyte conductivity and decreasing of activation energy.

The wastewater is potential processing facilities, from which you can receive bioenergy and biochemicals. Recovery of energy and valuable products can partially compensate for the cost of wastewater treatment and reduce some of the dependence on fossil fuels

This paper reviews the methods used nowadays for solid-oxide electrolyte film deposition. Problems and perspectives in the field of development of solid oxide fuel cells with film electrolyte are discussed.
