In this research,a conjugated Pc-MIL-88B(Fe)nanoplatform was constructed via a condensation process between modified zinc phthalocyanine and MIL-88B(Fe)for the removal of organic pollutants.The as-prepared material was fully characterized by TEM,XPS,ICP,FTIR,UV-Vis,N2 adsorption-desorption isotherm,etc.The results indicate that Pc-MIL-88B(Fe)preserved the topological structure of MIL-88B(Fe),and the micropores of framework could effectively prevent the aggregation of Pc in water.Meanwhile,the conjugated Pc-MIL-88B(Fe)basically maintains the singlet oxygen quantum yield of Pc,and behaves a much higher photocurrent intensity compared to NH2-MIL-88B(Fe).Additionally,the photosensitive activity and reusability of Pc-MIL-88B(Fe)were evaluated by the degradation of methylene blue in aqueous solution under visible light irradiation,and the degradation mechanism was also investigated in detail.
