Fig. 1: Schematic illustration of design protocol for the customization of porous heterojunction materials with superior reaction efficiency through energy-level modulation.

Mixed ligand (O: red; N: blue; C: gray); x stands for the average amino amount in UiO-66; Type-I and Type-II denote different heterojunction types. By engineering ligands to synthesize UiO-66 with varying energy levels and combining them with TDCOF, different porous heterojunction can be constructed to enhance the reactivity.
