Efficient three-phase electrocatalytic CO2 reduction to formate on superhydrophobic Bi-C interfaces

Bi-C catalysts with three-phase of CO2 (gas), electrolyte (liquid) and catalyst (solid) interfaces exhibit the remarkable electrocatalytic CO2 reduction (ECR) to formate selectivity (above 95 %Faradaic efficiency) with high current (100 mA cm-2) in a broad potential range.
