The NaBH4 Reduction and pH Effects on the Optical Property of Bismuth Vanadate
Published 2025-01-01“…In this study, oxygen vacancies were created on the surface of BiVO4 nanoparticles using the NaBH4 reduction technique, resulting in BiVO4−x samples that are oxygen-deficient. Optical absorption data using a UV-visible diffuse reflectance spectrophotometer showed that the reduction process increases the maximum absorption edge to 575 nm and reduces the band gap energy to 2.78 eV at high pH. …”
