Phosphorus leads to the best electron-accepting properties and increases fluorescence quantum yield in solution, silicon maximizes emission in the solid-state, whereas nitrogen leads to the smallest bandgap and promotes stronger intermolecular interactions. These findings offer key insights into structure–property relationships driven by main-group elements, establishing new design principles for the development of improved functional organic materials.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"35 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145035989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experiments showed that both of them exhibit high performance, which should be attributed to the abundant exposed active sites of their 2D structures.Hydrogen peroxide (H 2 O 2 ) usually serves as an environmentalfriendly strong oxidizing agent and a high-energy-density fuel, making it highly valuable across industrial, energy, and medical fields. [1][2][3] Currently, the predominant industrial method for H 2 O 2 production is the anthraquinone process, 4 which involves a multi-step synthesis that is energy-intensive and generates organic pollutants. Therefore, a more economical and environmental-friendly way to produce hydrogen peroxide is needed. To meet the demand of the growing market and environmental protection policy, various technologies of H 2 O 2 production have been developed, 5 among which, photocatalysis has been regarded as a revolutionary approach to green energy production. In H 2 O 2 production, the photocatalytic method enables the direct synthesis of H 2 O 2 through redox reactions using water, oxygen, and solar energy as raw materials. [6][7][8] This approach offers advantages such as mild reaction conditions, the absence of secondary pollution, and efficient solar energy conversion, highlighting its immense potential for future applications. Nevertheless, the fabrication of effective photocatalysts for H 2 O 2 production is still of great challenge.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"19 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145035581","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Molybdenum dioxide (MoO2) has garnered considerable attention due to its metallic-like high electrical conductivity and the intrinsic adsorption and activation capabilities of its surface-exposed Mo sites towards H+, O2, and H2O, making it a promising candidate for electrocatalytic water splitting with significant research value and application potential. This review summarizes recent advances in the synthesis methods, bulk and surface modification strategies for MoO2 nanoreactors, which have been employed to enhance their intrinsic catalytic activity. By integrating in situ characterization techniques with density functional theory (DFT) calculations, the review comprehensively elucidates the dynamic structural evolution and mechanistic insights of MoO2 nanoreactors during the catalytic process, providing a theoretical foundation for the rational design of MoO2 nanoreactors. The goal is to develop high-performance MoO2-based electrocatalysts through bulk and surface engineering to enhance efficient and sustainable hydrogen energy production, thereby offering theoretical insights into electrocatalytic water splitting.","PeriodicalId":67,"journal":{"name":"Chemical Communications","volume":"100 1","pages":""},"PeriodicalIF":4.9,"publicationDate":"2025-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145035991","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
