摘要：
BiVO4 and Ag-BiVO4 Nanoparticles were prepared using Azadirachta indica gum as a fuel via solution combustion synthesis (SCS) at 500 degrees C. From the PXRD, FTIR, UV-Visible DRS studies the synthesized NPs were characterized. The morphologies of the prepared NPs were studied by SEM and TEM analysis. The synthesized NPs were tested for photocatalytic and photoluminescence studies. The PXRD data indicated that the synthesized nanoparticles belong to monoclinic phase structure. The SEM data revealed that bead like structure were obtained. BiVO4 and Ag-BiVO4 Nps were taken to determine the photocatalytic activity on methylene blue dye. The results indicated that Ag-BiVO4 NPs exhibited promising photocatalytic activity due to the occurrence of Ag particles on the BiVO4 material, which makes the catalyst more sensitive and reduce the electron-hole recombination. Furthermore, the photoluminescence study reveals that Ag-BiVO4 nano particles shown blue light emission.
