Characterizations of MnO2 doped TiO2 nanostructures and effective degradation of methylene blue dye under visible light irradition

Pure and TiO2 doped MnO2 nanoparticles were made using a simple sol-gel technique, and their structural, morphological, characteristics were characteristically examined using XRD, FTIR, and UV-Visible and photocatalytic analysis. Through XRD and SEM analyses, a tetragonal crystalline structure with spherical nanoparticles was discovered. The EDAX experiments provide additional evidence of TiO2's presence in the MnO2 crystal matrix. From UV spectral studies, the band gap energy of MnO2 doped was determined. Photo-degradation study was monitored using methylene blue (MB) and phenol dye solution under visible light irradiation. MnO2 doped catalyst displayed exceptional photocatalytic efficacy towards MB dye under ideal conditions
