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. %O cited By 29; Conference of 3rd International Conference on Green Chemical Engineering and Technology: Materials Science, GCET 2017 ; Conference Date: 7 November 2017 Through 8 November 2017; Conference Code:140102 %L scholars10768 %J Materials Today: Proceedings %D 2018 %R 10.1016/j.matpr.2018.07.022 %N 10
