The effect of crystal facets and induced porosity on the performance of monoclinic BiVO4 for the enhanced visible-light driven photocatalytic abatement of methylene blue
In this study, a unique two-step approach has been developed to synthesize mesoporous BiVO4 (m-BiVO4) photocatalysts. The synthesized photocatalysts were characterized by means of XRD, SEM, EDS, UV-vis, Raman, PL, DRS, and N2-physiosorption analysis techniques. The hybrid BiVO4/KIT-6 composite and m...
