摘要
用动电位扫描和η（量子效率）～hv关系研究了钢电极在含或不含氯离子的硼砂－硼酸缓冲溶液中的电化学和光电化学行为.当溶液中不含氧离子时，铜电极呈p到光响应；相当量的氯离子存在对，光响应从p型转变为n型.研究表明p→n的转型不是由于电极表面生成了化合物CuCl，而应归因于氯离子对Cu2O膜的掺杂.
Electrochendcal and photoelectrochemical behavior for copper electrode in borax buffer solutions in the absence or in the presence of chloride ions were studied by potentiodynamic scan and photocurrent action spectrum. The photoresponse for Cu electrode in the absence of cliloride ions shows p-type and the photoresponse transition from p-type to n-type in the presence of chloride ions is attributed to Cu2O film doped by Cl-ions, not to the formation of CuCl.
