Prussian blue analogue heterointerface on a pre-oxidized copper foam surface for enhanced anodic oxidation performance

We developed CoFe-PBA on a pre-oxidized copper foam surface (CoFe-PBA@A-CF) for electrocatalytic benzyl alcohol oxidation. CoFe-PBA@A-CF decreased the cell voltage by 0.17 V in a two-electrode setup after substituting the OER with the BAOR. The pre-oxidation of CF enhanced the surface area and improved charge transfer, boosting the catalytic performance.
