In or on, a study of the influence of the binding site for TiO 2 and MIL-101(Cr)

In this work, TiO₂ was formed in situ in the internal pores and on the surface of MIL-101(Cr). Density functional theory (DFT) calculations demonstrate that the difference in the binding sites of TiO₂ can be attributed to the different solvents used. The two composites were used to photodegrade methyl orange (MO), and the photocatalytic efficiency of TiO₂-in-MIL-101(Cr) (90.1% in 120 min) was much stronger than that of TiO₂-on-MIL-101(Cr) (14% …
