The development of an efficient photocatalyst as a pollution-free technologies has garnered a lot of attention. Herein, monoclinic Bismuth Vanadate (BiVO4) with optimized photodegradation performance was synthesized via solid-liquid state reaction. The performance of developed BiVO4 was examined via degradation of methylene blue. This paper emphasized the role of electron-hole scavengers, namely hydrogen peroxide (H2O2), silver nitrate (AgNO3) and methanol (CH3OH) on optimizing the photodegradation activities of BiVO4. The obtained result concluded that the role of electron-hole scavengers is strongly dependent on the surface area of crystal planes of as-prepared BiVO4, namely 010 and 110 planes. The addition of AgNO3 shows the highest photocatalytic degradation activity, yielding 100 degradation of methylene blue in 120 minutes under visible-light-irradiation. The physicochemical properties of BiVO4 were characterized using Field-Emission Scanning Electron Microscope (FESEM), X-Ray diffraction (XRD), Fourier Transform Infrared (FTIR) and Brunauer-Emmet Teller (BET). © 2018 Elsevier Ltd.
