ConspectusTo cope with the increasingly global greenhouse effect and energy shortage, it is urgent to develop a feasible means convert anthropogenic excess carbon dioxide (CO2) into resources. The photocatalytic CO2 reduction reaction (CO2RR) coupled water oxidation (WOR), known as artificial photosynthesis, green, clean, promoting strategy deal above issues. Among reported systems for reduction, main challenge achieve WOR simultaneously due limited charge separation efficiency complicated dynamic process. To address problem, scientists have assembled two nanosemiconductor motifs CO2RR heterojunction photocatalyst realize photosynthesis. However, difficult clearly explore corresponding catalytic mechanism establish an accurate structure–activity relationship at molecular level their aperiodic distribution structural information.

Isoreticular Azobenzene Functionalization of Ultrastable Lead Chloride Hybrids for Enhanced Photocatalytic Aerobic Oxidation

ACS Materials Letters, Journal Year: 2024, Volume and Issue: 6(6), P. 2455 - 2464

Published: May 21, 2024

Lead halide hybrids have emerged as highly efficient photocatalysts, yet their application in photocatalytic organic synthesis remains limited, largely due to instability upon polar organics. Herein, we developed an isoreticular synthetic strategy functionalize lead chloride-based MOFs with azonbenzene units, a benchmark photoresponsive moiety. The three consist of isostructural 1D [PbCl]+ chains SBUs and biphenyl/azobenzene dicarboxylates struts. Compared the parent biphenyl-MOF, azobenzene-functionalized demonstrate broad wavelength coverage up 620 nm. Their photoinduced ligand-to-metal charge transfer affords enhanced electron–hole separation for long-lived free carriers. Among them, 4,4′-azobenzene-functionalized MOF exhibits most aerobic oxidation both C(sp3)-H photooxidation benzylamine coupling. Meanwhile, these coordination assembled exhibit high stability wide pH range compounds. This work showcases rational modify at molecular level while preserving lattice topology.
