The fully characterized Ag/C3N4 photocatalysts exhibited excellent stability and greatly enhanced visible light-driven photocatalytic performance both in the degradation of methyl orange (MO) and H2 evolution from water splitting. The 1.0 wt% Ag/C3N4 allowed the highest reaction rate of 0.0294 min−1 to be obtained in the MO degradation, which is about 2.3 times higher than the reaction rate of g-C3N4 alone of 0.0129 min−1. Furthermore, the optimum H2 evolution and the k value attained 20 µmol and 1.573 h−1, respectively, after 12 h of visible light irradiation. The surface plasmon resonance effect of Ag NPs and the charge transfer between the two components of the photocatalyst, strongly promote generation of photoinduced charge carriers while suppressing their recombination. These factors are held responsible for the enhanced visible light photocatalytic performance of Ag/C3N4. Our methodology will provide guidance for the design and synthesis of plasmon-enhanced visible light photocatalysts derived from Ag NPs and g-C3N4 and their applications in environmental remediation and green energy development.</div>","PeriodicalId":101081,"journal":{"name":"Resources Chemicals and Materials","volume":"1 1","pages":"Pages 1-7"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2772443321000040/pdfft?md5=77c55a72ad698e391536c54301bf3802&pid=1-s2.0-S2772443321000040-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86949922","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}

The oil content in a shale oil formation includes free oil contained in pores and trapped oil in the organic material called kerogen. The latter can represent a significant portion of the total oil and yet production of shale oil currently targets only the free oil rather than the trapped oil in kerogen. Shale oil reservoirs also have a substantial capacity to store CO2 by dissolving it in kerogen. In this paper, recent progress in the research of CO2-kerogen interaction and its applications in CO2 enhanced oil recovery and carbon sequestration in shale oil reservoirs are reviewed. The relevant topics reviewed for this relatively new area include characterization of organic matter, supercritical CO2 extraction of oil in shale, experimental and simulation study of CO2-hydrocarbons counter-current diffusion in organic matter, recovery of oil in kerogen during CO2 huff ‘n’ puff process, and changes in microstructure of shale caused by CO2-kerogen interaction. The results presented in this paper show that at reservoir conditions, supercritical CO2 can spontaneously replace the hydrocarbons from the organic matter of shale formations. This mass transfer process is the key to releasing organic oil saturation and maximizing the capacity of carbon storage of a shale oil reservoir. It also presents a concern of the structure change of organic materials for long term CO2 sequestration with shale or mudstone as the sealing rocks.</div>","PeriodicalId":101081,"journal":{"name":"Resources Chemicals and Materials","volume":"1 1","pages":"Pages 93-113"},"PeriodicalIF":0.0,"publicationDate":"2022-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S277244332200006X/pdfft?md5=6b9e140ce9b7c60715b640ab6e49fc15&pid=1-s2.0-S277244332200006X-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73294603","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}
