WebWe herein report that a thiocyanate ion (SCN –) switched the product selectivity of copper catalysts for eCO 2 RR in an H-cell. A cuprous thiocyanate-derived Cu catalyst was found to exhibit excellent HCOOH selectivity (faradaic efficiency = 70–88%) over a wide potential range (−0.66 to −0.95 V vs RHE).
