Construction of a self-supporting bifunctional Sn-SnSx electrocatalyst via one-step electrodeposition for formate production from coupled CO2 reduction and glucose oxidation

Sn–SnS x is used as a bifunctional electrode in a CO 2 RR//GOR coupling system, producing formate simultaneously at both the cathode and anode. This system combines the two pathways “CO 2 –HCOO − ” and “CO 2 –C 6 H 12 O 6 –HCOO − ”.
