Nanosized m-BiVO4 and Sr-doped derivatives were prepared by solid state reactions, to produce Bi1-xSrxVO4 (X = 0%, 4%, 8% & 12%). XRD and Raman investigations confirmed the formation of BiVO4 phase. 8% and 12% doped samples contained a small fraction of secondary t-BiVO4 phase. SEM images exhibited flat and irregular nanoparticles (64–70 nm). Estimated band gaps were in visible region (2.34–2.42 eV). The materials were used to photodegrade malachite green and BVO-12 showed maximum efficiency ˜ 88% in 180 min. The catalyst was stable and effective for three cycles. Radical scavenging experiments proved the role of holes and hydroxyl radicals. Polymer nanocomposite films made of EOC and photocatalyst were prepared. 0.15 g catalyst loaded film showed maximum activity and recyclability.
