分散めっきによるNi-AgBr感光性複合電極の作製

抄録

Preparation of a photosensitive composite electrode for an electrolytic cell aimed at energy conversion and photoredox reactions was attempted using the method of dispersion plating. Watt's bath containing photosensitive silver bromide powder as the dispersoid was used for dispersion plating. The conditions of current density, pH, and the rotation rate of the plating bath were investigated for the codeposition of matrix and dispersoid for preferable surface of the photosensitive electrode. The AgBr content also changed when these conditions changed. It was proven that were optimum conditions. The AgBr content increased about 1.6 times by addition of cationic surface active agent in comparison with the case that was not added. The composite electrode showed photosensitivity on the cyclic voltammetry under illumination by chopped light of Xe discharging lamp.
