Abstract

Mn-doped TiO2 nanomaterials were synthesized via the sol-microwave process. The microwave was used instead of the gel formation step in a conventional sol-gel method to shorten the reaction time. The physicochemical properties of the samples were evaluated by using respective modern characterization tools. The Mn-doping on TiO2 nanomaterial significantly improved the physical and chemical properties of the samples. Similarly, the outcome revealed the enhancement in photocatalytic performance of the Mn-doped TiO2. The efficient separation of photoelectron-hole pairs and increased light absorption ability in the UV and visible regions are the major reasons to improve the photocatalytic performance of the Mn-doped TiO2 for methylene blue degradation compared to the undoped materials
