| Abstract: | In this paper, in order to effectively improve the efficiency of the light absorption of catalysts and catalytic efficiency, carbon quantum dots (CQDs) were introduced into titanium-based metal organic framework material MIL-125, aiming to organically combine the advantages of high specific surface area and more catalytic sites of MOFs with the excellent optical properties of CQDs, and achieve synergistic effect. The morphology, structure and photoelectric properties of the composite photocatalyst were characterized. Its catalytic properties in the visible light catalytic degradation of organic dyes were systematically studied and the way of the introduction of CQDs effects on structure and performance of composite catalyst was explored. |
