摘要: ZnS quantum dots were impregnated on the surface of TiO2 mesospheres by a soft template-assisted solvothermal approach. XRD and elemental analysis confirmed presence in nanostructures. Morphological showed that firmly immobilized mesospheres, which improved electron hole pair separation at TiO2/ZnS interface. The photocatalytic activity mesoporous nanostructures was assessed photodegradation methylene blue (MB) as model pollutant under visible light irradiation. Impregnation with enhanced reaction remarkably compared TiO2. maximum degradation efficiency observed for 0.025 M MB-related absorption peak completely disappeared after 32 min Photo-charge scavenger indicated hydroxyl radicals played pivotal role mechanism. photocatalyst stable can be used repeatedly
