Electrochemical synthesis of catalytic active alloys

Abstract

The aspects of man-caused gaseous waste purification from hydrocarbons, nitrogen oxides and carbon using supported catalytic neutralizers are analyzed. The replacement of platinum metals in catalysts by alloys and oxide compounds is discussed to be an actual task. The use of hydrogen release reaction is proposed to estimate the catalytic activity of synthesized materials. Electrochemical methods are shown to be of good prospects in catalytic material design. Current exchange dependence on "metal-hydrogen" and "metal-oxygen" bond energy is used for alloy property prediction. The modes for synthesis of nickel-palladium, nickel-copper and nickel-tungsten alloys with maximum catalytic activity are optimized. The synergism of nickel-tungsten and nickel-copper alloys is shown.
