The anode material is one of the determining factors for success electrowinning process. This study aims to coat graphite substrate with β-PbO2 produce an inert graphite/β-PbO2 composite low cost and good quality. synthesis expected be used as composites processes. deposition layer was prepared on surface by electrodeposition process using a sulfuric acid electrolyte. effect electrolyte concent...

The problems related to the electrochemical/electrocatalytic stability of perchlorate ions are reviewed in the light of recent experimental results. The electrocatalytic, catalytic, and electrochemical reduction processes are presented and the links between them are outlined. Some possible mechanisms of the complicated reduction processes are discussed. Various methods for the detection of redu...
