| 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. |
