The accessible fly ash-based ceramic membrane (CM) underwent hydrophobic modification through silane grafting, followed by fluoroalkylsilane decoration, to prepare the superhydrophobic membrane (CSCM). The CSCM significantly improved resistance to wetting by the biphasic solvent, consisting of amine (DETA) and sulfolane (TMS). Morphological characterizations and chemical analysis revealed the notable enhancements in pore structure and hydrophobic chemical groups for the modified membrane. Predictions of wetting/bubbling behavior based on static wetting theory referred the liquid entry pressure (LEP) of CSCM increased by 20 kPa compared to pristine CM. Compared with traditional amine solvents, the biphasic solvent presented the expected phase separation. Performance experiments demonstrated that the CO capture efficiency of the biphasic solvent increased by 7%, and the electrical energy required for desorption decreased by 32%. The 60-h continuous testing and supplemental characterization of used membrane confirmed the excellent adaptability and durability of the CSCMs. This study provides a potential approach for accessing hydrophobic ceramic membranes and biphasic solvents for industrial CO capture.","PeriodicalId":12744,"journal":{"name":"Green Energy & Environment","volume":"23 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2024-07-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141935020","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The asymmetric membrane comprises a dense SrFeTaO (SFT) separation layer and a porous Sr(FeTa)CuO (SFTC) catalytic layer. In the first stage reactor, a CO splitting reaction (CDS: 2CO→2CO+O) occurs at the SFTC catalytic layer. Subsequently, the O product is selectively extracted through the SFT separation layer to the permeated side for the methane combustion reaction (MCR), which provides an extremely low oxygen partial pressure to enhance the oxygen extraction. In the second stage, a Sr(FeTa)NiO (SFTN) catalyst is employed to reform the products derived from MCR. The two-stage CMR design results in a remarkable 35.4% CO conversion for CDS at 900 °C. The two-stage CMR was extended to a hollow fiber configuration combining with solar irradiation. The solar-assisted two-stage CMR can operate stably for over 50 hours with a high hydrogen yield of 18.1 mL min cm. These results provide a novel strategy for reducing CO emissions, suggesting potential avenues for the design of the high-performance CMRs and catalysts based on perovskite oxides in the future.","PeriodicalId":12744,"journal":{"name":"Green Energy & Environment","volume":"134 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2024-07-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141779681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, developing efficient electrocatalysts featuring desirable activity and selectivity is still a big challenge. In this work, a strategy of introducing functionalized molecules with desirable CO affinity to regulate Ag catalyst for promoting electrochemical reduction of CO was proposed. Specifically, 3-mercapto-1,2,4-triazole was introduced onto the Ag nanoparticle (Ag-m-Triz) for the first time to achieve selectively converting CO to carbon monoxide (CO). This Ag-m-Triz exhibits excellent performance for CO reduction with a high CO Faradaic efficiency (FE) of 99.2% and CO partial current density of 85.0 mA cm at −2.3 V vs. Ag/Ag in H-cell when combined with the ionic liquid-based electrolyte, 30 wt% 1-butyl-3-methylimidazolium hexafluorophosphate ([Bmim][PF])-65 wt% acetonitrile (AcN)-5 wt% HO, which is 2.5-fold higher than the current density in Ag-powder under the same condition. Mechanism studies confirm that the significantly improved performance of Ag-m-Triz originates from (i) the stronger adsorption ability of CO molecule and (ii) the weaker binding energy to form the COOH∗ intermediate on the surface of Ag-m-Triz compared with the Ag-powder catalyst, which boosts the conversion of CO to CO. This research provides a facile way to regulate electrocatalysts for efficient CO reduction by introducing functionalized molecules.","PeriodicalId":12744,"journal":{"name":"Green Energy & Environment","volume":"414 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2024-07-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141779730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Results from both experiments and density-functional theory (DFT) calculations indicate the separation and transfer of the photoinduced charges is highly related to the triazine-N content and the conjugation degree in the skeletons of COFs. High-efficiency CO photoreduction can be achieved by rationally adjusting the number and position of both benzene and triazine rings in the COFs. Specifically, TTA-TTB, with orderly interlaced triazine-benzene heterojunctions, can suppress the recombination probability of electrons and holes, which effectively immobilizes the key species (COOH) and lowers the free energy change of the potential-determining step, and thus exhibits a superior visible-light-induced photocatalytic activity that yields 121.7 μmol HCOOH g h. This research, therefore, helps to elucidate the effects of the different structural blocks in COFs on inherent heterogeneous photocatalysis for CO reduction at a molecular level.","PeriodicalId":12744,"journal":{"name":"Green Energy & Environment","volume":"78 1","pages":""},"PeriodicalIF":13.3,"publicationDate":"2024-07-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141586145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, its cyclability is poor because of harmful side reactions at the LiPSCl/Li interface and growth of lithium dendrites inside LiPSCl phase. Herein, we report a simple interface-engineering remedy to boost the electrochemical performance of LiPSCl, by coating its surface with a Li-compatible electrolyte LiOCl having low electronic conductivity. The obtained LiPSCl@LiOCl core@shell structure exhibits a synergistic effect. Consequently, compared with the bare LiPSCl, this composite electrolyte exhibits great performance improvements: 1) In Li|electrolyte|Li symmetric cells, the critical current density at 30 °C gets increased from 0.6 mA cm to 1.6 mA cm, and the lifetime gets prolonged from 320 h to 1400 h at the cycling current of 0.2 mA cm or from 6 h to 900 h at the cycling current of 0.5 mA cm; 2) In Li|electrolyte|NCM721 full cells running at 30 °C, the cycling capacity at 0.2 C (or 0.5 C) gets enhanced by 20% (or from unfeasible to be feasible) for 100 cycles and the rate capability reaches up to 2 C from 0.2 C; and in full cells running at 60 °C, the cycling capacity is increased by 7% at 0.2 C and the rate capability is enhanced to 3.0 C from 0.5 C.

This work proposes an active learning workflow (LeNN) founded on local electronic transfer features () and the principle of coordinate rotation invariance. By accurately characterizing the electron transfer to adsorption site atoms and their surrounding geometric structures, LeNN mitigates abrupt feature changes due to different element types and clarifies coordination environments. As a result, it enables the prediction of ∗H adsorption energy on binary oxide surfaces with a mean absolute error (MAE) below 0.18 eV. Moreover, we incorporate local coverage () and leverage neutral network ensemble to establish an active learning workflow, attaining a prediction MAE below 0.2 eV for 5419 multi-∗H adsorption structures.

The highest photocatalytic performance was obtained through crystallinity and homojunction engineering, by controlling the pgCN:CC3N5 ratio.
