- Strategical engineering of semiconducting films by loading co-catalysts is pivotal for optimizing the properties of photoelectrodes used for solar fuel production. In this study, an ultrathin layer of cobalt phytate (CoPhy) was integrated onto the nanoporous bismuth vanadate (BiVO4) photoanode by a simple photo-assisted electrodeposition method. The introduction of CoPhy significantly improved the PEC performance of BiVO4 photoanode, displaying a photocurrent density up to 4.3 mA cm-2 at 1.23 V (vs. reversible hydrogen electrode (RHE), AM 1.5G) and an impressive early onset of potential of ~0.2 VRHE as well as superior stability. Moreover, charge kinetics studies showed that the enhancement in PEC performance by CoPhy is primarily due to the suppression of surface recombination and acceleration of interfacial charge transfer.
