The predictability of MOFs' structure and function also make it possible to use computational methods to advance and accelerate research. This review gives a brief overview of carbon dioxide capture and separation by MOFs, including adsorption and membrane separation. In the future, membrane separation technology is expected to be a crucial area of research for carbon capture applications due to its favorable characteristics such as high treatment efficiency and low carbon footprint, while mixed matrix membranes (MMMs) have been given more attention by scholars due to their lower cost and better separation performance.

However, the influence of precipitant quantity on both morphology evolution and SC performance has been an underexplored area. This study systematically examines the morphological changes in CoNi‐LDHs by varying the alkaline quantity and evaluates the performance of asymmetric SC. The findings reveal a progressive transformation in the morphology of CoNi‐LDHs with an increase in alkaline content, starting from nanorod (Co1Ni2(OH)2‐1HMA), progressing to nanorod/nansosheet composite (Co1Ni2(OH)2‐4HMA), and ultimately evolving into nanosheet (Co1Ni2(OH)2‐8HMA). This evolution is attributed to the synergetic effect of the precipitant and variable cobalt, which provides multiple valences and induces morphology evolution. The resulting LDHs demonstrate different SC performances: (1) Co1Ni2(OH)2‐1HMA exhibits a maximum capacitance of 1764 F/g, while Co1Ni2(OH)2‐4HMA and Co1Ni2(OH)2‐8HMA show values of 1460 F/g and 1676 F/g, respectively; (2) rate capabilities showcase percentages of 60.5% for Co1Ni2(OH)2‐1HMA, 83.1% for Co1Ni2(OH)2‐4HMA, and 66.3% for Co1Ni2(OH)2‐8HMA; (3) maximum energy densities are recorded at 72.1 Wh/kg for Co1Ni2(OH)2‐1HMA, 41.3 Wh/kg for Co1Ni2(OH)2‐4HMA, and 62.8 Wh/kg for Co1Ni2(OH)2‐8HMA. Particularly, Co1Ni2(OH)2‐8HMA exhibits superlong cycling stability, retaining approximately 99% capacitance after 25000 consecutive charge/discharge cycles at 7.0 A/g. This result underscores its significant potential for efficient energy storage applications.","PeriodicalId":100387,"journal":{"name":"EcoEnergy","volume":"52 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138946288","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This review diligently summarizes both the seminal work and ongoing developments pertaining to 2D semiconductor nanosheets and their application to solar energy within the context of heterogeneous photocatalysis. We begin by detailing the distinctive properties of 2D semiconductor nanosheets, concentrating on their pivotal roles in augmenting photocatalytic efficiency, and explaining the intrinsic mechanisms that govern the migration rate of photogenerated carriers on the material's surface. Subsequently, we delineate the methods employed to synthesize typical 2D semiconductor nanosheets. In alignment with the overarching objective of expanding light absorption capacity and accelerating charge transfer, we also examine the current research on the hybridization techniques involving 2D materials of varied dimensions, as well as their deployment in diverse photocatalytic applications.

As a result, DTCN demonstrates a higher photocatalytic hydrogen evolution rate (1440 μmol·g−1·h−1), which is 5 times higher than that of the initial g‐C3N4 nanotube (TCN). Importantly, combined with density functional theory calculations and experimental results, it is the first time to prove that the synergy of curvature effect and N vacancy of nanotubes can enhance the adsorption energy of hydrogen and decrease the work function, resulting in more superior photocatalytic performance than the layered structure.

However, controlling oxygen content to realize the best match of water dissociation and hydrogen adsorption is challenging. Herein, we exploit the self‐integration process of MoNi alloy in molten salts to introduce oxygen atoms, which ultimately leads to the localized generation of robust NiOxHy around the MoNi alloys. Interestingly, Mo is further doped into NiOxHy (Mo‐NiOxHy) to construct an effective active center for water dissociation due to the high mobility in ionic solutions. Owing to the covering and space confinement of molten salt, MoNi alloy is exactly decorated with Mo‐NiOxHy nanosheets. Both physical characterization and density functional theory calculation prove that the electron transport, water dissociation capability, and hydrogen adsorption of MoNi are finely tuned and benefited from the O and Mo doping, thus greatly expediting HER kinetics. Mo‐NiOxHy exhibits a much lower overpotential of 33 mV at 10 mV cm−2 in alkaline electrolyte, even superior to the Pt/C benchmark. Moreover, the final Mo‐NiOxHy requires a low overpotential of 57 mV at 10 mV cm−2 in acidic media. This enhancement is ascribed to the successful assembly of MoNi foam elicited by molten salt.","PeriodicalId":100387,"journal":{"name":"EcoEnergy","volume":"6 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138952924","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this work, a universal thermal model for lithium ion batteries (LIBs) was proposed, which was validated by using commercially available 18650 batteries as well as testing the electrochemical parameters of a Poly(ethylene oxide)(PEO)–bis(trifluoromethane)sulfonimide lithium salt(LiTFSI)–Li2MnO3(LMO) (PLL) composite solid‐state electrolyte (CSSE), while a computational model was developed for all‐solid‐state LIBs (ASSLIBs) based on PLL CSSE. The simulation results show that the maximum temperature of ASSLIBs based on PLL CSSE and commercial standards are both significantly lower than the thermal runaway temperature of solid‐state electrolyte. However, as the temperature of the battery varies greatly under different operating conditions, it will cause great difficulties in the control of other ancillary components and even finally lead to certain safety issues. Therefore, from the perspective of performance and practical application, the CSSE should be improved toward improving the ionic conductivity at low temperatures to have more commercial prospects, and lower interfacial impedance and a higher lithium ion migration number would also be beneficial for optimizing the thermal behavior of ASSLIBs to achieve better commercial prospects.","PeriodicalId":100387,"journal":{"name":"EcoEnergy","volume":"56 29","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138588195","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Electrochemical nitrogen (N2) reduction reaction (ENRR) emerges as the most attractive pathway to produce NH3. The process utilizes H2O as a proton source under mild temperature and pressure, which can reduce CO2 emissions and energy input compared to the traditional Haber-Bosch process. However, ENRR is severely insufficient for practical applications due to its kinetically sluggish steps compared to its competitive hydrogen evolution reaction. Also, the imbalanced reactant concentrations of N2 and H2O, resulting from the low N2 solubility, and oppositely, free H2O accessibility toward catalysts, cause the ineffective three-phase-boundary that acts as active sites for ENRR. To overcome these challenges, it is essential to perform interfacial engineering for each part of the catalyst and reaction environment. In this perspective, recent advances in interfacial engineering are examined and critically reviewed, and further research directions are proposed to develop ENRR significantly. The sections cover catalytic active site modification, hydrophobic/hydrophilic control, electrolyte engineering, and system design. The insights and prospects in this perspective will be effective for developing ENRR in a scientific and practical manner.","PeriodicalId":100387,"journal":{"name":"EcoEnergy","volume":"1 1","pages":"3-15"},"PeriodicalIF":0.0,"publicationDate":"2023-11-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ece2.10","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136347199","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}
