Liu, G., Eichhorn, J., Jiang, C.-M., Scott, M., Hess, L., Gregoire, J., Haber, J., Sharp, I., Toma, F. Interface engineering for light-driven water oxidation: Unravelling the passivating and catalytic mechanism in BiVO4 overlayers. Sustainable Energy Fuels, DOI: 10.1039/C8SE00473K (2018).
We synthesized (NiFeCoCe)Ox multi-functional coating on BiVO4 photoanodes that exhibit nearly 100% efficient surface collection of holes under oxygen evolving reaction conditions
Significance & impact
The complementary use of macroscopic photoelectrochemical measurements and nanoscale atomic force microscopy techniques provide foundational knowledge of interface engineering in integrated photoactive materials for solar fuel production
We enhanced charge transport and collection of photogenerated holes at the BiVO4/catalyst interface
The (CoFeCe)Ox excels at efficient capture and transport photogenerated holes, and (NiFe)Ox at reducing charge recombination at the BiVO4/electrolyte interface
