This review explores these fundamental challenges and outlines the latest developments in the field of UHMWPE. The recent developments of catalysts, processing and modification methods of UHMWPE, and the applications of UHMWPE are discussed in detail.

MOFs have garnered considerable interest in energy storage, primarily for supercapacitor applications because of their exceptionally high surface area, tunable porosity, and structural versatility. This review highlights the electrochemical behavior of MOFs, their charge storage mechanisms, particularly electric double-layer capacitance and pseudo-capacitance, as well as their synthesis routes using solvothermal, microwave-assisted, and hydrothermal methods. Such enhancement of capacitance and rate capability results from the incorporation of MOFs with conductive materials such as graphene quantum dots and metal oxides. Specific cases involving Ni-MOF, Co-MOF, and NbSn-MOF composites are discussed, with a focus on their structural properties, electrochemical performance, and potential application prospects. Thereafter, the environmental sustainability aspects, challenges, and future directions of MOF-based supercapacitors are discussed.</div></div>","PeriodicalId":374,"journal":{"name":"Journal of Organometallic Chemistry","volume":"1042 ","pages":"Article 123866"},"PeriodicalIF":2.1,"publicationDate":"2025-09-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145218764","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review examines the synthesis strategies, structural characteristics, and catalytic properties of these hybrid materials. Chitosan, a biocompatible and biodegradable polysaccharide, serves as a versatile support due to its functional groups, which facilitate strong metal coordination and allow for easy chemical modification. When combined with superparamagnetic Fe₃O₄ nanoparticles, the resulting composite catalyst enables magnetic separation and recyclability with no substantial reduction of activity or metal leaching. Recently, magnetic Chitosan-supported Pd NPs catalysts have emerged as an eco-friendly, practical, and highly effective choice for facilitating the Suzuki reaction.
