镍在碱溶液中阳极膜的形成和性质与化学电源和金属腐蚀等有关．在这方面已有较深入的研究报导．其研究方法也是多种多样，除一般的电化学方法［１，２］外，还有许多现场谱学方法，如：紫外＿可见光谱［３］，红外光谱［４］，光热光谱［５］，拉曼光谱［６］，椭圆法［７...
The influence of heat on the measurement of photocurrent for nickel electrode in 1 mol/L NaOH solution was investigated by using the photocurrent,photothermal and thermal current methods. It was found that the appearance of photocurrent in potential region of -0.750.20 V(vs. Hg/HgO electrode) was due to the p_type semiconductor properties of Ni(OH)2 film in which is agree with the previous report. In the Ni(OH)2/NiOOH redox potential region, the increase of temperature at the surface of working electrode during irradiation significantly promoted the electrochemical reaction strongly. The photocurrent observed in potential region 0.200.57 V is mainly attributed to the influence of heat produced upon irradiation. This is contrary to the view of the photoelectrochemical properties of the semiconductor reported in literature.
