We create the active electrocatalysts and sudy the kinetics of electrode processes which take place in energy storage devices. In particular, we developed the electrochemical techniques of catalyst fabrication, which allow to control metal quantity in the catalysts with the low content of platinum group metals. We also worked out the approach to regulate metal content and dispersion in the catalyst by means of changing the nature of the support, deposition potential, and electrolyte composition.<\/p>\n

Our recent research is concentrated on galvanic replacement and electrochemical leaching as the tools to fabricate active\u00a0 catalysts for oxidation of small organic molecules (\u0421\u041d3<\/sub>\u041e\u041d, \u041d\u0421\u041e\u041e\u041d, etc).\u00a0 Our goal is to decrease the content of the platinum group metals and to increase their specific activity by combining these noble metals with less expensive components\u00a0 (e.g., \u0421u, Bi, Pb). We were lucky to prepare a number of structures being of practical interest for fuel cells which operate with organic fuels. Our work is also essential for further understanding of electrochemical oxidation of \u041d\u0421\u041e-species. This scientific direction was started in 1960th under supervision of A.N. Frumkin.<\/p>\n

We cooperate with Prof. V.V. Kuznetsov (Mendeleev University of Chemical Technology)\u00a0 in the studies of platinum group metals modified with molybdenum oxocompounds. Galvanic replacement of molybdenum was demonstrated to be prospective for fabrication of the mixed catalysts (Pt, Pd \u2013 molybdenum oxides).\u00a0The electroless Pd eposition on molybdenum bronzes resulted in the catalyst with activity comparable to Pt activity in respect to methanol oxidation.<\/p>\n
