[Display omitted] •Pure BiVO4 nanostructures were synthesized by environmental friendly Co-precipitation method.•The indirect bandgap of BiVO4 was observed 2.5 which is well matched with literature.•Pure BiVO4 NPs showed almost 88% efficient degradation of methylene red dye. For the enhancement of degradation of methylene red dye pure BiVO4 NPs have been synthesized. For this purpose, a simple, inexpensive, and efficient co-precipitation has been used to synthesize pristine BiVO4 NPs. The two basic precursors such as bismuth nitrate and ammonium metavanadate were utilized for synthesis and sodium hydroxide was utilized to maintain the pH of the synthesized nanostructures. Using various characterization techniques for instance UV–visible spectroscopy, photoluminescence spectroscopy, scanning electron microscopy, energy dispersive x-rays, and, Fourier transform infrared spectroscopic analysis, the optical properties, morphological characteristics, elements analysis, structural properties, and information about functional groups have been termed. An indirect band gap (2.5 eV) of the synthesized BiVO4 has been observed. Because NPs are smaller reduced, they have a higher advanced surface-to-volume ratio, which adds additional active adsorption sites and increases the catalyst’s photocatalytic activity. The degradation efficiency of the photocatalysts is 88.2%. The photocatalytic activity of the medicine Synflex was also performed, and it was experimental that the dye has much degradation efficiency compared to the medicine. This excellent degradation efficiency of the synthesized photocatalyst makes it acceptable for the degradation of organic pollutants. The antimicrobial activity of pure BiVO4 against two different bacteria showed outstanding results.
