Electrochemical properties of nanodispersed diamond

Abstract

The object of this work was to investigate hydrogen oxidation and oxygen reduction from surface of modified nanodispersed diamond. The catalytic reactions on the surface of nanodispersed diamond have been studied after different treatment using heat-treated and electrochemical methods. For developing the modifying of nanodispersed diamond there have been proposed the following treatment: - special heat-treated treatment in hydrogen environment; - (hydrogen electrode); - precipication of palladium (oxygen electrode). It has been established that special heat-treated treatment to surface of nanodispersed diamond effective for hydrogen electrode material creation. Precipication of palladium of nanodispersed diamond surface it to be saturated with atomic oxygen. The quantity of atomic oxygen is higher than that of molecular oxygen. It has been shown that nanodispersed diamond. after precipication of palladium are effective catalyst of oxygen reduction. © 2007 Springer.
