In recent years, porphyrins have been frequently reported as photocatalysts due to their fascinating photochemical properties. However, the same shortcomings other homogeneous photocatalysts, such poor stability and difficulty in recovering. To solve this problem, it is a good strategy form porphyrin-based metal-organic framework (PMOF) by modifying porphyrin functional groups adding metals nodes connect control arrangement of porphyrins. The metal rigidity connectivity modules order them MOF, which improves porphyrins, avoids aggregation folding, increases active sites for photocatalytic reactions. This review summarized research progress PMOF last ten years analyzed effects spatial structure, ligands, central metals, on performance. applications PMOF-based H

Metal-free polymeric carbon nitride (PCN) materials are at the forefront of photocatalytic applications. Nevertheless, overall functionality and performance bulk PCN limited by rapid charge recombination, high chemical inertness, inadequate surface-active sites. To address these, here, we employed potassium molten salts (K+X-, where X- is Cl-, Br-, I-) as a template for in situ generation surface reactive sites thermal pyrolyzed PCN. Theoretical calculations imply that addition KX to PCN-forming monomers causes halogen ions be doped into C or N with relative trend ion doping being Cl < Br I. The experimental results show reconstructing develops newer beneficial catalysis. Interestingly, H2O2 rate KBr-modified was 199.0 μmol h-1, about three times Owing simple straightforward approach, expect salt-assisted synthesis have wide exploration modifying activity.
