摘要: 光透薄层电极(OTTLE)在给定的电位下可测定介稳化合物的可见光谱,我们首次将它用于CO2电催化还原机理的研究,并检测到CO2钴卟啉配合物中间体和确定了催化机理。光透薄层电极池的工作电极是甩0.01mm金丝网,面积为0.5×2.0cm2,网孔密度为每厘米宽度内约含100根金丝。

Abstract: In this work, optically transparent thin-layer electrode (OTTLE) was used to detect the intermediate of electrocatalytic reduction of CO2The results showed that in the presence of imidazole (Im),the intermediate CO2·Co(Ⅰ) TMAPI·lm, was detected by UV/Vis absorption pectrum at -1.0V (SCE). The characteristic peaks were 434.0nm, 555.4nm and 603.6nm. We can come to the concolusion that CO2was activated by the formation of the intermediate CO2-Co(Ⅰ)-TMAPI.
