Abstract

Hydrogen is produced in this study by direct electrolysis at 1000 Am-2 in 0.5M NaCl solution of pH 2 at room temperature. Direct and pulse current electro-deposition methods have been applied to the preparation of MnMo-oxide anode deposited on IrO2/Ti substrate. The beneficial effects of pulse deposition and timings on the performance of MnMo-oxide anodes during electrolysis and the physicochemical properties of the deposits were characterized using SEM and electrochemical techniques.
