Regulating the H₂O₂ Photosynthetic Activity of Covalent Organic Frameworks through Linkage Orientation

ACS Catalysis, Journal Year: 2024, Volume and Issue: 14(7), P. 4728 - 4737

Published: March 13, 2024

Imine-linked isomeric covalent organic frameworks (COFs) with opposite linkage orientations are not rare, but their structure and photocatalytic property corrections still puzzling, let alone the emerging photosynthetic H2O2 performance. Herein, a pair of COFs (TB-COF TA-COF) reversed imine linkages was fabricated. Compared to TA-COF, TB-COF exhibited larger dipole moments better charge carrier separation efficiency, resulting in superior photosynthesis capability via dominant oxygen reduction reaction (ORR) paths (O2–O2•––H2O2 O2–O2•––O21–H2O2) feeble water oxidation (WOR) paths. With no sacrificial agents air, rates were 5186 μmol g–1 h–1 4111 natural seawater, respectively. The seawater-produced can be directly utilized for tetracycline degradation, manifesting big picture wastewater treatment by H2O2. Theoretical calculations revealed that hydroxyl-rich benzene ring photooxidation part triazine unit primary photoreduction part. Through linkage-orientation regulation, electronic structures, migration property, energy barrier rate determination step 2e– ORR WOR well-modulated. current work provides insight into effect orientation on performance may enlighten design catalysts photosynthesis.

Surface Engineered Single‐atom Systems for Energy Conversion

Advanced Materials, Journal Year: 2024, Volume and Issue: 36(16)

Published: Jan. 10, 2024

Abstract Single‐atom catalysts (SACs) are demonstrated to show exceptional reactivity and selectivity in catalytic reactions by effectively utilizing metal species, making them a favorable choice among the different active materials for energy conversion. However, SACs still early stages of conversion, problems like agglomeration low conversion efficiency hampering their practical applications. Substantial research focus on support modifications, which vital SAC stability due intimate relationship between atoms support. In this review, category supports variety surface engineering strategies employed SA systems summarized, including site (heteroatom doping, vacancy introducing, groups grafting, coordination tunning) structure (size/morphology control, cocatalyst deposition, facet engineering, crystallinity control). Also, merits single‐atom systematically introduced. Highlights comprehensive summary discussions utilization surface‐engineered diversified applications photocatalysis, electrocatalysis, thermocatalysis, devices. At end potential obstacles using field discussed. This review aims guide rational design manipulation target‐specific capitalizing characteristic benefits engineering.
