Effective and comprehensive implementation of VOC prevention is an arduous task. Catalytic oxidation can achieve VOC removal with low energy costs and high efficiency. This review presents representative research progress in thermal or photothermal catalysis over the past ten years, concentrating on various catalysts with distinctive morphologies and structures designed and prepared for investigating single- or multi-component VOC purification, synergetic elimination of VOCs and NO<sub><em>x</em></sub>, and VOCs resource utilization. Furthermore, the influence mechanisms of H<sub>2</sub>O, CO<sub>2</sub>, and SO<sub>2</sub> on the catalytic stability are summarized. The activity and stability of the catalysts affect their lifespan and cost of use. In particular, for supported noble-metal catalysts with poor stability, some unique design strategies have been summarized for the efficient removal of VOCs while balancing low noble-metal usage and optimized catalytic performance. Finally, the scientific problems and future research directions are presented. Coordinated treatment of atmospheric pollutants and greenhouse gases should be considered.

Herein, we proposed a “solvent-scissors” strategy for overcoming the inert hydrogen bonding, enabling the efficient aerobic oxidation of methyl aromatics into aromatic acids under atmospheric oxygen at 25–45 °C. The hydrogen bonds between the key intermediate, benzaldehyde (PhCHO), and hexafluoroisopropanol (HFIP) were reconstructed using solvent-scissors (acetic acid (HOAc), ethyl acetate, ethyl chloroacetate, and methyl chloroacetate), which promoted the release of free PhCHO from its inert hydrogen-bonded state and enabled the one-step oxidation of toluene to benzoic acid under mild conditions. The standard Gibbs free energy changes (Δ<em>G</em><sup>0</sup>) representing the proton acceptance capability of the solvent were of the same order of magnitude as the turnover number (TON) (capacity for promoting benzaldehyde oxidation). This approach affords remarkable benzoic acid selectivity (98.7%) with high toluene conversion (96.8%) at 45 °C within 4 h under 0.1 MPa O<sub>2</sub> using NHPI/metal acetate/HFIP-HOAc.

The biocatalytic module was built by converting photo-induced electrons to enhance NADH regeneration; thus, the NADH content in <em>E. coli</em> under blue light increased by 5.1-fold compared to that in darkness. Finally, IBPHS was utilized to drive CO<sub>2</sub> reduction pathways for versatile bioproduction such as formate and pyruvate, with CO<sub>2</sub> utilization rates up to 51.98 and 21.92 mg/gDCW/h, respectively, exceeding that of cyanobacteria. This study offers a promising platform for the rational design of biohybrids for efficient biomanufacturing processes with high complexity and functionality.</p></div>","PeriodicalId":9832,"journal":{"name":"Chinese Journal of Catalysis","volume":"60 ","pages":"Pages 294-303"},"PeriodicalIF":16.5,"publicationDate":"2024-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141084144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
