Solar vapor generators (SVGs) have recently shown promising results to be used as a cleaner alternative water harvesting system for desalination application. However, recent SVGs using semiconductor as photo-thermal materials (PTMs) still suffer from a low average water evaporation performance. This study aims to develop a novel high-water generating hydrogel-based SVG consisting of cross-linked polyvinyl alcohol (PVA) matrix and designed MnO<sub>2</sub> nanorods as solar-to-heat converter. Results indicated that the resultant hydrogel material exhibited a maximum water evaporation rate of 2.8 kg/(m<sup>2</sup>·h) under 1 sun. Furthermore, the PVA/MnO<sub>2</sub> hydrogel demonstrated salt resistant and filtration capability for desalination application with a consistent evaporation rate of 2.8 kg/(m<sup>2</sup>·h) and >99.8% reduction of sodium ion concentration. In short, this study opens up a new pathway for the development of high performance SVG system for desalination applications.</p></div>","PeriodicalId":100481,"journal":{"name":"Environmental Functional Materials","volume":"1 2","pages":"Pages 196-203"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2773058122000230/pdfft?md5=ad2c4a87ced789a4af9f9a167114ab65&pid=1-s2.0-S2773058122000230-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71874950","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}

Immobilization techniques onto supports are summarized and discussed, including membrane-based reaction systems (immersion mode, and filtration mode), electrocatalytic auxiliary systems, and alternative supports (metallic glasses, aerogels, hydrogels, and specific materials).

Various treatment technologies have been developed for the remediation of this waste, including degradation, recycling and upcycling, and transformation to value-added products has been extensively studied. Transitioning plastic waste into carbon-based functional materials is especially attractive because of the practical applications of plastic wastes derived carbon materials (PWCMs) in the field of green energy and in sustainable environmental practices. Herein, recent advances in the preparation and applications of PWCMs are systematically reviewed. Thermal treatment methods for synthesizing carbon-based materials from plastic waste are summarized, including anoxic pyrolysis, catalytic and pressure carbonization techniques, flash Joule heating and microwave conversion. The applications of PWCMs and PWCMs-based composites to green energy storage and production (such as in batteries, supercapacitors and water-splitting systems) and sustainable environmental concepts (pollutant adsorption/degradation, solar evaporation and CO<sub>2</sub> capture) are detailed, with an emphasis on the property-performance correlation. The potential for future development of PWCMs is also examined. This review is meant to provide insights into the advanced applications of PWCMs and to stimulate the future upcycling of plastic waste.</p></div>","PeriodicalId":100481,"journal":{"name":"Environmental Functional Materials","volume":"1 1","pages":"Pages 34-48"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2773058122000096/pdfft?md5=443237b2b5a1994ed0da13e1bad5516e&pid=1-s2.0-S2773058122000096-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"71900097","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}
