ACS Catalysis, Journal Year: 2024, Volume and Issue: 14(11), P. 8694 - 8719

Published: May 20, 2024

Microplastics (MPs, particle size < 5 mm) have become increasingly ubiquitous on Earth due to the cleavage and degradation of heavy use plastics. MPs recently been reported be detected in human blood, alveoli, breast milk, embryos, other organs, raising concerns about their environmental risks. Photocatalysis has identified as a potential means for conversion, which utilizes solar energy stimulate semiconductor photocatalyst. However, study photocatalytic conversion is still incubation period. This review overviews current state-of-the-art technologies conversion. Then, fundamental principles, challenges, analytical techniques, evaluation indexes reforming are highlighted. We systematically summarized recent advances key factors influencing performance. Finally, we propose some perspectives developing efficient systems MPs. will provide guideline applying technology MPs, significantly contribute this emerging research field.

Stepwise Protonation of Three‐Dimensional Covalent Organic Frameworks for Enhancing Hydrogen Peroxide Photosynthesis

Angewandte Chemie International Edition, Journal Year: 2024, Volume and Issue: 63(30)

Published: May 13, 2024

Abstract Three‐dimensional covalent organic frameworks (3D COFs), recognized for their tailorable structures and accessible active sites, offer a promising platform developing advanced photocatalysts. However, the difficulty in synthesis functionalization of 3D COFs hinders further development. In this study, we present series 3D‐ bcu ‐COFs with 8 connected porphyrin units linked by linear linkers through imine bonds as versatile photocatalyst design. The photoresponse was initially modulated functionalizing benzo‐thiadiazole or benzo‐selenadiazole groups. Furthermore, taking advantage well‐exposed sites ‐COFs, photocatalytic activity optimized stepwise protonation centers. dual protonated COF groups exhibited enhanced charge separation, leading to an increased H 2 O production under visible light. This enhancement demonstrates combined benefits linker on efficiency.

Artificial photosynthetic system for diluted CO2 reduction in gas-solid phase

Nature Communications, Journal Year: 2024, Volume and Issue: 15(1)

Published: Oct. 11, 2024

Rational design of robust photocatalytic systems to direct capture and in-situ convert diluted CO2 from flue gas is a promising but challenging way achieve carbon neutrality. Here, we report new type host-guest photocatalysts by integrating CO2-enriching ionic liquids photoactive metal-organic frameworks PCN-250-Fe2M (M = Fe, Co, Ni, Zn, Mn) for artificial photosynthetic reduction in gas-solid phase. As result, [Emim]BF4(39.3 wt%)@PCN-250-Fe2Co exhibits record high CO2-to-CO rate 313.34 μmol g−1 h−1 under pure atmosphere 153.42 (15%) with about 100% selectivity. In scaled-up experiments 1.0 g catalyst natural sunlight irradiation, the concentration could be significantly decreased below 85% 10%, respectively, indicating its industrial application potential. Further theoretical calculations reveal that not only benefit enrichment, also form synergistic effect Co2+ sites PCN-250-Fe2Co, resulting significant Gibbs energy barrier during rate-determining step conversion. Artificial fuel authors system frameworks, greatly enhancing conversion efficiency.
