Although water electrolysis has emerged as a core technology for hydrogen production, its advancement remains constrained by the exorbitant cost, scarcity, and inadequate stability of precious metal catalysts. Transition metal selenides (TMSes) has emerged as promising electrocatalytic materials due to their combined advantages of low cost, tunable electronic structures, and intrinsic activity comparable to noble metals. This review focuses on multidimensional engineering strategies to systematically analyze the performance optimization mechanisms of TMSes in hydrogen evolution reaction and oxygen evolution reaction. Five key aspects are comprehensively discussed: conductive substrate engineering, interfacial synergy effects, crystal facet and morphology regulation, cation/anion doping strategies, and single-atom catalyst construction. Research demonstrates that the synergistic effects of multidimensional strategies can overcome the intrinsic limitations of TMSes, including restricted conductivity, active site passivation, and stability deficiencies. This establishes a theoretical framework for designing efficient-stable-low-cost water electrolysis catalysts. Future studies should integrate in situ characterization with machine learning-assisted computations to unveil the dynamic reaction interfaces and structural evolution patterns.","PeriodicalId":10046,"journal":{"name":"Chemical record","volume":" ","pages":"e2500082"},"PeriodicalIF":7.0,"publicationDate":"2025-06-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144316008","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}

Several conventional wastewater treatment methods, including flocculation and coagulation, photocatalysis, membrane systems, and adsorption, have been shown to be efficient and limited in their ability to remediate harmful contaminants. However, the rate of achievement observed with all of these methods is frequently connected with the effectiveness and sustainability of the wastewater treatment materials utilized. Metal-organic frameworks (MOFs) have emerged as a promising solution, offering diverse morphological and chemical properties, such as high surface areas, pore volumes, and tailored regions. This present review focuses on the structural characteristics of MOFs, including surface area, porosity, thermal stability, and adaptability. Sustainable synthesis methods and the applications of MOFs in wastewater treatment through adsorption and photocatalysis of pollutants like dyes, heavy metals, and organic contaminants are discussed. Finally, the existing challenges and limitations of MOF-based wastewater treatment are addressed, and future research prospects are outlined. The unique properties of MOFs make them promising materials for extensive applications, with significant potential for industrial prospects.","PeriodicalId":10046,"journal":{"name":"Chemical record","volume":" ","pages":"e2500076"},"PeriodicalIF":7.0,"publicationDate":"2025-06-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144215100","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}

This structural alteration significantly influences their chemical reactivity, enzymatic stability, and biological function, making them valuable tools for drug design, nucleotide-based enzymatic studies, and synthetic biology applications. In this review, we explore the synthetic methodologies employed for constructing 5'-O-P-N linkages, including phosphoramidation strategies, catalytic approaches, and emerging green chemistry techniques.
