Abstract: Carbon quantum dots doped octahedral bipyramids TiO2 with high exposed (101) reactive facets and carbon quantum dots doped nanosheets TiO2 with high exposed (001) reactive facets were successfully fabricated by facile solvothermal process. The catalysts were characterized using TEM,XRD and XPS measurements. They confirm that the carbon quantum dots were uniformly integrated to TiO2. The catalytic activity of the as-prepared catalysts in degradation of rhodamine B in aqueous solution under visible light irradiation (λ ≥ 400 nm) was systematically investigated. The experiments show that the doping of carbon quantum dots in TiO2 can substantially improve the photo degradation efficiency relative to pure TiO2, both for octahedral bipyramids TiO2 and nanosheets TiO2. Generally, the photodegradation efficiency of (101) facet exposed octahedral bipyramids TiO2 is prevailing over that of (001) facet exposed nanosheets TiO2. |
