主 题：NH2-MIL-88(Fe) N-TiO2 Photocatalysis Fenton effect
摘 要：Core-shell TiO2-based photocatalysts with specific composition,morphology,and functionality have attracted considerable attention for their excellent degradation properties on organic pollutants via a photocatalytic oxidation ***,a N-TiO2@NH2-MIL-88(Fe)core-shell structure was prepared by coating NH2-MIL-88(Fe)on nitrogen-doped TiO2(N-TiO2)*** of heteroatom nitrogen to pure TiOz expands the spectra response range,leading to enhanced quantum efficiency of *** NH2-MIL-88(Fe)or N-TiOz improved the adsorption ability of the nanocomposites due to the porous tunnels of NH2-MIL-88(Fe).The resulted core-shell N-TiO2@NH2-MIL-88(Fe)nanocomposites realized the transfer of photo excited electrons from N-TiOz to NH2-MIL-88(Fe)rapidly,partially reduced Fe to Fe^2+in NH^2+MIL-88(Fe),and further enhanced the Fenton effect on efficiently degrading methylene blue dye(MB)under visible light(420 nm)with the assistance of H2O2.
