초록
Mn-doped TiO2 nanomaterials were synthesized via the sol-microwave process. The microwave was used instead of the gelformation step in a conventional sol-gel method to shorten the reaction time. The physicochemical properties of the sampleswere evaluated by using respective modern characterization tools. The Mn-doping on TiO2 nanomaterial significantlyimproved the physical and chemical properties of the samples. Similarly, the outcome revealed the enhancement inphotocatalytic performance of the Mn-doped TiO2. The efficient separation of photoelectron-hole pairs and increased lightabsorption ability in the UV and visible regions are the major reasons to improve the photocatalytic performance of the MndopedTiO2 for methylene blue degradation compared to the undoped materials.
