Cu-nanocluster-loaded N-doped porous graphitic carbon for electrochemical CO 2 reduction towards syngas generation.

In this study, a novel electrocatalyst, namely Cu/N- pg -C derived from Cu-doped ZIF-8, was investigated for making syngas products with various H 2 /CO ratios. Different ratios of the electrocatalytic syngas products CO and H 2 could be selected by adjusting the applied potential and hence tuning the transfer of electrons from N-doped graphitic carbon to the well-dispersed Cu nanoclusters.
