At present, a variety of catalyst modification strategies have been developed, but the corresponding photocatalytic performance is not ideal. The key to improving the efficiency of photocatalysis is the effective separation and transfer of photogenerated carriers. The electromagnetic effect of magnetic field will affect the spin state and the motion mode of electrons, so it is feasible to enhance the photocatalytic performance with external magnetic field. Additionally, the magnetic field has the advantages of simplicity, non-contact, environmental friendly, and high efficiency which is more in line with the policy requirement of green energy development and utilization. In this paper, the main theories of magnetic field enhanced photocatalysis are reviewed and the mechanism of magnetic field enhanced photocatalysis is explained from three aspects: spin polarization, Lorentz force, and magnetoresistance effect. Then combined with the application of magnetic field in photocatalytic CO<sub>2</sub> reduction, water decomposition, wastewater treatment, and N<sub>2</sub> fixation, the enhancement strategies of various photocatalysts were summarized. Finally, the challenges and potential application value of magnetic field enhanced photocatalytic performance were presented, providing corresponding theoretical basis and experimental guidance for subsequent research.</p></div>","PeriodicalId":100486,"journal":{"name":"Environmental Surfaces and Interfaces","volume":"1 ","pages":"Pages 10-23"},"PeriodicalIF":0.0,"publicationDate":"2023-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2949864323000036/pdfft?md5=b8e668393bff4f5e1575c613edbffc18&pid=1-s2.0-S2949864323000036-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138611148","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, two artificial light-harvesting systems with an efficient energy transfer were constructed successfully in the aqueous media based on sulfobutylether-β-cyclodextrin (β-CD) and curcumin (Cur) through host-guest interactions, in which two different fluorescence dyes, sulforhodamine (SR101) and Nile blue (NiB) were employed as energy acceptors. The obtained artificial LHSs can achieve an efficient energy transfer process from β-CD+Cur to SR101 or NiB with energy transfer efficiencies of up to 16.3% and 15.8%, respectively. The energy harvested by the acceptors (SR101 and NiB) was used for photocatalysis in the aqueous phase dehalogenation of the α-bromoacetophenone reaction with a yield of up to 80%.</p></div>","PeriodicalId":100486,"journal":{"name":"Environmental Surfaces and Interfaces","volume":"1 ","pages":"Pages 3-9"},"PeriodicalIF":0.0,"publicationDate":"2023-09-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49735569","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
