Boosting CO₂ Photoreduction via Regulating Charge Transfer Ability in a One‐Dimensional Covalent Organic Framework

Angewandte Chemie International Edition, Journal Year: 2023, Volume and Issue: 62(46)

Published: Sept. 28, 2023

Two-dimensional (2D) imine-based covalent organic frameworks (COFs) hold potential for photocatalytic CO2 reduction. However, high energy barrier of imine linkage impede the in-plane photoelectron transfer process, resulting in inadequate efficiency photoreduction. Herein, we present a dimensionality induced local electronic modulation strategy through construction one-dimensional (1D) pyrene-based (PyTTA-COF). The dual-chain-like edge architectures 1D PyTTA-COF enable stabilization aromatic backbones, thus reducing loss during exciton dissociation and thermal relaxation, which provides energetic to traverse linkages. As result, exhibits significantly enhanced photoreduction activity under visible-light irradiation when coordinated with metal cobalt ion, yielding remarkable CO evolution 1003 μmol g-1 over an 8-hour period, surpasses that corresponding 2D counterpart by factor 59. These findings valuable approach address charge limitations COFs.

Angewandte Chemie International Edition, Journal Year: 2023, Volume and Issue: 62(30)

Published: April 28, 2023

Metal-free covalent organic frameworks (COFs) have been employed to catalyze the oxygen reduction reaction (ORR). To achieve high activity and selectivity, various building blocks containing heteroatoms groups linked by imine bonds were used create catalytic COFs. However, roles of linkages COFs in ORR not investigated. In this work, linkage engineering has modulate behaviors. single sites while avoiding other possible sites, we synthesized from benzene units bonds, such as imine, amide, azine, oxazole bonds. Among these COFs, oxazole-linkage enables with highest activity, which achieved a half-wave potential 0.75 V limited current density 5.5 mA cm-2 . Moreover, oxazole-linked COF conversion frequency (TOF) value 0.0133 S-1 , 1.9, 1.3, 7.4-times that azine-, amide- imine-COFs, respectively. The theoretical calculation showed carbon atoms facilitated formation OOH* promoted protonation O* form OH*, thus advancing activity. This work guides us on are suitable for ORR.
