Mesoporous strontium doped ZnO nanoparticles are synthesized as photocatalyst by using zinc nitrate hexahydrate, surfactant P123, strontium nitrate hexahydrate via the hydrothermal process. X-ray diffraction (XRD), UV-visible spectroscopy (UV), Fourier transform infrared (FTIR), Photoluminescence (PL), Energy-dispersive x-ray (EDX), Scanning electron microscopy (SEM), Transmission Electron Microscopy (TEM), and Brunauer–Emmett–Teller (BET) characterizations are used for the analysis of all the samples. XRD spectra disclose the disparity in the crystal size 14.98 to 22.74 nm. The study of UV spectroscopy revealed the energy bandgap difference between 3.3–2.92 eV. PL spectroscopy shows the effect of doping on the electron-hole recombination rate of the sample. FTIR analysis has utilized to determine the functional groups such as –OH, C=O=C, and –C–O present in the sample. EDX spectra show the elemental compositions of the sample. SEM images show the agglomerated morphology and TEM...
