WebSep 4, 2024 · The observation of a spontaneous electron enrichment at the apexes of bismuth vanadate (BiVO 4) nanopyramidal arrays is achieved by performing synchrotron-based angular dependent X-ray absorption spectroscopy. In accordance with density function theory calculations, the formation of (112) facets enriched apexes is proposed. Centimeter‐sized monoclinic BiVO4 (BVO) crystals are successfully grown by Bridgman method, and the physical and chemical properties of their exposed crystal surfaces have been studied. It is found that the atomic alignment and atomic density on different types of crystal facets of BiVO4 are different, which results in …
