Abstract In the present work, Nickel doped Molybdenum trioxide (NixMoO3) where Ni = X (X = 5, 10, and 15%) nanoparticles (NPs) were synthesized by a wet chemical method. These nano crystals are structurely analysized by X-ray diffraction and confirm the formation of orthorhombic structure in both MoO3 and Ni-doped MoO3 samples. The impact of Ni doping on crystallite size, micro strain, and texture co efficient are obtained from XRD pattern. The morphology studies of FE-SEM and HR-TEM show that the presence of one dimensional (1D) nanorods with an average diameter of particle size around 28–32 nm and the compositional stoichiometry is confirmed by EDAX technique. The functional group and the vibrational mode of metal oxide (Mo = O) are confirmed by FT-IR spectra. The photocatalytic activities of pure and Ni-doped MoO3 are attributed to the degradation efficiency under UV–Visible light irradiation. The result shows that these structure exhibits promising degradation of Methylene blue (MB) is calculated along with the kinetic study, cyclic efficiency, and growth mechanism. The ability of the catalysts generates electron-hole pairs which create free radicals and also help to undergo the secondary reactions. The MoO3 and Ni-doped MoO3 samples normally reveal better results against in antibacterial activity such as Escherichia Coli (E. Coli) and Staphylococcus aureus (S. aureus) bacteria. Overall, the results demonstrate that the doping of Ni2+ ions inside the MoO3 matrix enhances the performance in antibacterial activity.
