A competing reaction, called the hydrogen evolution reaction (HER) or “water splitting,” takes precedence over the CO 2 conversion reaction. One reason is that it performs HER very well, and brings down the CO2 reduction selectivity dramatically. This study was supported in part by the Rowland Institute at Harvard University.
