DOI: 10.1021/acsami.2c09032

Abstract: For the efficient photocatalytic oxidation of organic pollutants at surfaces of semiconductors, photogenerated holes shall be separated toward the surface and transferred to reactive surface sites, whereas the transfer of photogenerated electrons toward the surface… read more here.

DOI: 10.1021/jacs.3c10627

Abstract: Two-dimensional covalent organic frameworks (COFs) are an emerging class of photocatalytic materials for solar energy conversion. In this work, we report a pair of structurally isomeric COFs with reversed imine bond directions, which leads to… read more here.

DOI: 10.1039/d2cc03333j

Abstract: The role of the coordination solvent in MOFs with photocatalysis can't be ignored. Novel [Ni(PTCA)·sol]-MOFs with a 3D open wavy-layered structure are selected for in-depth study by imitating the internal environment of a chameleon. The… read more here.
