Primary challenges in electrochemical CO 2 reduction lie with its product selectivity and competitive hydrogen evolution reaction (HER). Therefore, selective CO 2 reduction with less hydrogen evolution or without any hydrogen evolution is very essential for industrial interests. In this study, we report a selective electrochemical CO 2 reduction at a boron‐doped diamond electrode modified with Cu nanoparticles in ionic liquid. In addition to the improved product selectivity, control of the competitive HER was also achieved in this work.
