| 摘 要： | 用光电化学方法研究棒状和多孔氧化银电极在阳极极化过程中的光响应规律可以得到许多信息。最大光响应出现在电极表面的AgO被充分地还原为Ag_2O以及Ag结晶即将生成瞬间, 多孔电极和实体电极开路光电位ΔV_(ph,oc)之比有助于对多孔电极孔结构的了解, 首次观测到n-p-n光响应波形的转化。

| Abstract: | Both wire and porous AgO electrodes were studied using photoelectrochemical method during their cathodic polarization. Much information has been available through their photoresponse measurements. The maximum open-circuit photopotential ΔV_(Ph, oc) occurred at the moment when the surface of electrode was fully covered with Ag_2O and dendritic Ag was just about to appear. The ratio of ΔV_(Ph, oc) for these two electrodes may be related to the pore configaration of the porous electrode. The photoresponse waveforms of n-p-n transition were first seen by means of signal averaging technique. |
