A new type of composite catalyst AmCoPc/UiO-66-NH2 synergistic photocatalytic degradation of dyes

A new type aminophthalocyanine was synthesized and loaded on MOFs material UiO-66-NH2 by impregnation method to synthesize a new type binary composite catalyst AmCoPc/UiO-66-NH2. It was systematically characterized by X-ray powder diffraction (XRD), Fourier transform infrared (FT-IR), X-ray photoelectron spectroscopy (XPS), Scanning electron microscopy (SEM) and N2 adsorption desorption. The synthesized catalyst was applied to the photocatalytic degradation of methylene blue dye under visible light. Compared with AmCoPc or UiO-66-NH2 monomer performance, the synthesized AmCoPc/UiO-66-NH2 composite significantly enhanced the degradation of methylene blue (MB), the best degradation efficiency was 90.32%. The reason is that the synergistic effect of AmCoPc and UiO-66-NH2 effectively improves the light utilization efficiency. The desirable properties such as the positive catalytic activity of the central ion and the high specific surface area of the composites accelerate charge transport and reduce charge recombination.
