Battery chemistry largely determines individual cell performance as well as the battery pack cost and life cycle greenhouse gas emission. Continuous manufacturing platforms improve production efficiency in terms of product yield, quality and cost. Spent-battery recycling ensures the circular economy of critical elements that are required for cathode production.

The performance of COFs in photocatalysis is underpinned by the intrinsic tendency of charge separation and transfer, thereby depending on the molecular building blocks. Benzobisthiazole (BBT), with an electron-withdrawing effect, shows superior potential in various optoelectronic materials. Therefore, with tetrabutylammonium hydroxide as a catalyst, a fully conjugated COF, BBT-sp2c-COF, is synthesized from 2,2′-(benzo[1,2-d:4,5-d′]bis(thiazole)-2,6-diyl)diacetonitrile and 1,3,6,8-tetrakis(4-formylphenyl)pyrene. As such, a series of characterizations demonstrate the structural and optical properties of BBT-sp2c-COF. The fully conjugated COF, BBT-sp2c-COF, possesses enhanced charge separation, electron transfer, and recycling stability. As expected, BBT-sp2c-COF photocatalysis achieves effective selective oxidation of benzyl amines with oxygen under blue light irradiation. Superoxide is identified as the crucial reactive oxygen species during the formation of imines. The full conjugation of organic building blocks into COFs can achieve highly effective photocatalysis.","PeriodicalId":104,"journal":{"name":"Sustainable Energy & Fuels","volume":" 2","pages":" 527-537"},"PeriodicalIF":5.0,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142976336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This addresses both the challenges of sustainable energy and waste management. In this study, RDF waste is utilized in a plasma gasification unit integrated with combined cycle, molten carbonate fuel cell (IPGCC-MCFC) and chemical looping reforming (IPGCC-CLR) systems for the co-generation of hydrogen and electricity. The simulations of the proposed plants are conducted using Aspen Plus software, and subsequently, the techno-economic assessment and life cycle analysis are performed. The results indicated that the highest net overall energy efficiency of 66.05%, lowest cost of electricity of 74.90 $ per MW h and levelized cost of hydrogen of 1.02 $ per kg, can be obtained for the IPGCC-CLR system. This improved the energy return on investment to 2.89 MW/MW as compared to 1.69 MW/MW for the IPGCC-MCFC plant. The life cycle analysis estimated the total fossil fuel consumption of 5.06–6.16 MJ s−1 and CO2 emissions of 285.14–335.61 gCO2eq. s−1 throughout the project duration. The plants reduce fossil fuel consumption by 1.5 times and CO2 emissions by 3 times as compared to the reported literature. Moreover, the analyses of other factors of environmental impact types of acidification potential, eutrophication potential, human toxicity potential, etc., show that the RDF processing stage contributes the largest pollution, followed by hydrogen compression and the transportation stage. The emissions can be minimized by replacing fossil fuels with hydrogen-based products at every stage.","PeriodicalId":104,"journal":{"name":"Sustainable Energy & Fuels","volume":" 2","pages":" 627-639"},"PeriodicalIF":5.0,"publicationDate":"2024-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142976355","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, the occurrence of side reactions is inhibited by anode alloyage, electrode or electrolyte additives, or altering the structural design of the electrode. Among them, altering the structural design can effectively enhance the cycling performance. Furthermore, the 3D interconnected network structure can realize a uniform electric field and ion distribution to improve the electrode reaction behavior. Inspired by this, a ZnO anode with a 3D cross-linked network structure was constructed using CNFs as the 3D skeleton. By regulating the ZnO content and the ratio of CNFs/CB in the ZnO@CNFs/CB materials, the effect of the component content on the performance of the ZnO anodes was analyzed. With the increase in ZnO contents and CNFs/CN ratios, the reversibility, hydrogenation inhibition effect, cycling performance and rate performance of the ZnO anodes first showed an increasing trend, followed by a decreasing trend. When the theoretical mass ratio (ZnO : CNFs : CB) between the components in the ZnO@CNFs/CB material was 8 : 1 : 1, it exhibited a high hydrogenation inhibition effect and reversibility. When the prepared materials were used as the ZnO anode material of the zinc–nickel battery, the specific discharge capacity after 600 cycles at 1C rate was 566.90 mA h g−1, the coulombic efficiency was 86.02%, and the capacity retention rate was 90.17%. The average specific discharge capacity was 602.66 mA h g−1.","PeriodicalId":104,"journal":{"name":"Sustainable Energy & Fuels","volume":" 2","pages":" 490-500"},"PeriodicalIF":5.0,"publicationDate":"2024-12-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142976311","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This involved facile treatment of the material with aqueous HCl to induce defects that generated free carboxylic acid (–COOH) groups. Consequently, the modified UiO-66 framework incorporated both Brønsted acidic –COOH groups and Lewis acidic sites, which originate from inherent linker-missing defects. These dual-functional acidic sites, combined with the high structural stability of UiO-66, enable it to act as an efficient heterogeneous catalyst for one-pot, multistep reactions. Specifically, the catalyst facilitates the conversion of glucose to levulinic acid (LEV) in the presence of sodium chloride (NaCl) as a promoter under hydrothermal conditions. Under optimized conditions (190 °C for 6 h), the catalytic system achieves a remarkable conversion of glucose (>99%), with an impressive 83% yield of LEV. The defect-engineered UiO-66 catalyst shows exceptional potential as a candidate for sugar conversion to valuable bio-based chemicals.","PeriodicalId":104,"journal":{"name":"Sustainable Energy & Fuels","volume":" 2","pages":" 596-605"},"PeriodicalIF":5.0,"publicationDate":"2024-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142976342","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, embedded nanosheets and plates of cobalt oxy carbide (Co–O–C/CPs) were successfully synthesized as an efficient bifunctional electrocatalyst using a solvent-free combustion process. To contribute to the clarification of catalytic particle composition during electrochemical reactions, we thoroughly characterized the Co–O–C/CPs using HR-TEM, which revealed that the filled nanoplates, with a cobalt oxide shell and cobalt carbide core, were wrapped with carbon. During electrochemical reactions, the filled nanoplates changed to an amorphous state owing to the decomposition of the crystalline material. After amorphization, the Co–O–C/CPs maintained the shape of the parent compound and exhibited a higher electrochemically active surface area (ECSA) and thereby demonstrated enhanced HER (115 mV) and OER (240 mV) performances at 10 mA cm−2. When applying the Co–O–C/CPs as both the cathode and anode, a lower cell voltage of 1.60 V was required at 10 mA cm−2 than that for the benchmark catalyst IrO2/Pt/C/NF (1.63 V) with great stability in alkaline solution.
