Abstract: We worked on the facile solution combustion reaction to obtain GdVO 4 nanoparticles by using peroxovanadate gel for the first time as a precursor, gadolinium nitrate as an oxidizer, and tartaric acid as a fuel. The synthesized nanoparticles were used to investigate the photocatalytic activity against methylene blue dye and antimicrobial activity. The powder X-ray diffraction analysis reveals the generation of GdVO 4 nanoparticles having a tetragonal phase with a crystallite size of ~ 18 nm. Scanning electron micrograph (SEM) images exhibit a porous environment of the product. Brunauer Emmett-Teller surface area analysis of GdVO 4 nanoparticles indicates a relatively sizable specific surface area of ~ 44.5 m 2 g –1 . Transmission electron microscopy exhibits a regular distribution of particles with a standard particle size varying in the range of 30–90 nm. The band gap of 2.5 eV is projected using the Ultraviolet DRS spectrum of GdVO 4 nanoparticles. The photoluminescence spectrum unveils an emission peak at 470 nm. The environmental degradation of methylene blue (MB) dye using GdVO 4 nanoparticles as a photocatalyst exhibits ~ 90% of decolorize in the presence of visible light radiation. Also, the inhibiting the growth of microorganism activity of GdVO 4 nanoparticles was tested against E- coli, Streptococcus mutants, Aspergillus niger and Candida albicans and it was found to be possessing inhibiting property.
