Electrosynthesis of nanocomposite materials for electrocatalysis

摘要: A review of the studies carried out during last decade on electrosynthesis oxide–matrix composite materials for electrocatalysis is presented. The anodic deposition composites from electrolytes containing either Pb2+ or Tl+ ions and catalytic (nano)particles in suspension produces electrocatalytic especially suitable processes (oxygen evolution reaction) owing to oxides stability towards oxidative degradation. embedding conducting particles may have a major effect nucleation growth matrix, leading very rough porous deposits. content dispersed phase cannot be increased at will. However, volume fractions order 0.1–0.2, attained without difficulty, are high enough ensure marked effects. In comparison with pure matrices, anodes exhibit much lower overpotantials Tafel slopes, comparable those produced by other methods.
