摘要：

A ternary composite alpha-DMACoPc/UiO-66-NH2/TiO2 was synthesized by solvothermal method and characterized by X-ray powder diffraction (XRD), X-ray photoelectron spectroscopy (XPS), Fourier transform infrared (FT-IR), scanning electron microscopy (SEM) and other means. The composite catalyst was applied to decompose methylene blue dye in visible light, and the degradation rate reached 93.4%. Compared with the monomer, the composite significantly enhanced the efficiency of the catalytic degradation due to the synergistic effect between composites. The transport speed of charge is accelerated and the recombination of hole-electron pairs is inhibited due to the larger specific surface area. A feasible scheme was provided for preparation of composite catalyst and photocatalytic degradation of dye. [GRAPHICS]
