【摘要】 本文研究了支持电解质KCl浓度对n—InP光电化学稳定性的影响,指出在pH=1的饱和KCl溶液中,光照时能够形成1—2个分子层厚度的表面氧化膜,这层膜的存在能够保护电极免受光腐蚀,而不降低光生空穴的界面迁移速度。更多还原

【Abstract】 The influence of the concentration of the electrolyte KCl on photoelectrochemical behavior of n-InP Photoanode has been studied. The surface film with the thickness of 5-10A could be formed during the illumintion in the highly concentrated KCl solution. In the presence of this oxide layer, not only the dissolution rate could be reduced, and the position of the energe band could be altered.Both ef- fects result in the stabilization of the n-InP photoanode.更多还原
