Sacrificial agent-free photocatalytic CO₂ reduction using a 2D cobalt porphyrin-based MOF/graphene heterojunction

Abstract

2D MOFs show great potential in photocatalysis owing to their ultrathin thickness, large surface area and highly accessible active sites. Nevertheless, the studies applying 2D MOF as photocatalyst are very...

Metal– and covalent organic frameworks for photocatalytic CO2reduction coupled with H2O oxidation

“…Recently, some semiconductors ( e.g. , graphene, 125–127 Cu 2 O, 128 TiO 2 , 129,130 CsPbBr 3 , 131,132 Bi 2 S 3 , 133 Cd 0.2 Zn 0.8 S, 134 etc .) have also been employed to construct Z-scheme heterojunctions.…”

Bimetallic Fe/Co photothermal catalyst for fixing CO2 to cyclic carbonates under atmospheric pressure

“…For instance, Dong et al 35 successfully modified the Ni-MOF-74 material by regulating the temperature and solvent to achieve a highly porous structure and introduce ligand defects, thereby enhancing its photocatalytic CO 2 conversion performance. Cheng et al 36 effectively constructed a novel cobalt MOF catalyst by coupling a 2D cobalt porphyrinyl MOF with graphene, enabling efficient photo-catalysis of CO 2 reduction without the need for any sacrificial agent or photosensitizer. Bimetallic MOFs exhibited superior performance in CO 2 catalysis compared to monometallic MOFs.…”
