Abstract

Abstract : Light Aging In article number 2200132, Camilo A. Mesa, Sixto Giménez, Elena Mas‐Marzá, and co‐workers demonstrated through electrochemical and microstructural analysis that oxygen vacancies correlate with a migration of Bi towards the BiVO4 surface. Light‐aging has shown to increase the efficiency of BiVO4 photoanodes due to oxygen vacancies modulation but establishing chemical changes has been challenging. Highly efficient photoelectrochemical oxidation reactions are key for solar‐to‐fuel synthesis.
