摘要: This paper describes the photocatalytic degradation of methylene blue (MB) in aqueous solution presence TiO2 nanoparticles (NPs) different compositions anatase and rutile phases under UV light irradiation. The crystalline NPs were synthesized using sol-gel method at same temperature for various calcination times. subjected to crystal phase, vibrational, size, morphological characterizations. MB revealed that have a superior catalytic activity front phase. finding further suggested low charge resistance electron-hole recombination probability lead acceleration OH• formation on surface NPs.
