摘要：

A combinatorial approach is described for screening homogeneous CO2 reduction electrocatalysts by means of a high-throughput 25-well parallel electrolyzer. Active catalysts were then screened by three methods: (1) the presence of CO gas in the electrolyzer head space; (2) a pH change for the individual solutions before and after bulk electrolysis due to proton consumption during CO2 reduction; and (3) other physical attributes. Based on these screening methods, two solutions out of the 25 were selected for further study. One out of two selected solutions, nickel cyclam, a well-known CO2 reduction electrocatalyst, was correctly identified to be the most active.
