Herein, novel NiIn based catalysts were developed by tailoring Ni catalysts with Indium (In) for this reaction. Over the optimal Ni0.1Zn0.7Al0.3InOx catalyst, the ethyl acetate selectivity reached 90.1% at 46.2% ethanol conversion under the conditions of 548 K and a weight hourly space velocity of 1.9 h-1 in the 370 h time on stream. Moreover, the ethyl acetate productivity surpassed 1.1 gethyl acetate gcatalyst-1 h-1, one of the best performance in current works. According to catalyst characterizations and conditional experiments, the active sites for dehydrogenative coupling of ethanol to ethyl acetate were proved to be Ni4In alloys. The presence of In tailored the chemical properties of Ni, and subsequently inhibited the C-C cracking and/or condensation reactions during ethanol conversions. Over Ni4In alloy sites, ethanol was dehydrogenated into acetaldehyde, and then transformed into acetyl species with the removal of H atoms. Finally, the coupling between acetyl species and surface-abundant ethoxyde species into ethyl acetate was achieved, affording a high ethyl acetate selectivity and catalyst stability.","PeriodicalId":12744,"journal":{"name":"Green Energy & Environment","volume":"185 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"135660784","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}

Sodium-ion batteries (SIBs) have attracted extensive attention and are recognized as ideal candidates for large-scale energy storage due to the abundant sodium resources and low cost. Sodium metal anodes (SMAs) have been considered as one of the most attractive anode materials for SIBs owing to their high specific capacity (1166 mAh g<sup>−1</sup>), low redox potential, and abundant natural resources. However, the uncontrollable dendrite growth and inevitable side reactions on SMA lead to the continuous deterioration of the electrochemical performance, causing serious safety concerns and limiting their practical application in the future. Therefore, the construction of stable dendrite-free SMAs is a pressing problem for advanced sodium metal batteries (SMBs). In this review, we comprehensively summarize the research progress in suppressing the formation of sodium dendrite, including artificial solid electrolyte interphase (SEI), liquid electrolyte modification, three-dimensional (3D) host materials, and solid-state electrolyte. Additionally, key aspects and prospects of future research directions for SMAs are highlighted. We hope that this timely review can provide an overall picture of sodium protection strategies and stimulate more research in the future.</p></div>","PeriodicalId":12744,"journal":{"name":"Green Energy & Environment","volume":"8 5","pages":"Pages 1279-1307"},"PeriodicalIF":13.3,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50175612","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, conventional simple pyrolysis of biomass always generates inadequate porosity with limited surface area. Moreover, biomass-derived carbon also suffers from poor wettability and single physical adsorption of ions, resulting in limited desalination performance. Herein, pore structure optimization and element co-doping are integrated on banana peels (BP)-derived carbon to construct hierarchically porous and B, N co-doped carbon with large ions-accessible surface area. A unique expansion-activation (EA) strategy is proposed to modulate the porosity and specific surface area of carbon. Furthermore, B, N co-doping could increase the ions-accessible sites with improved hydrophilicity, and promote ions adsorption. Benefitting from the synergistic effect of hierarchical porosity and B, N co-doping, the resultant electrode manifest enhanced CDI performance for NaCl with large desalination capacity (29.5 mg g<sup>−1</sup>), high salt adsorption rate (6.2 mg g<sup>−1</sup> min<sup>−1</sup>), and versatile adsorption ability for other salts.

Several techniques, such as TEM, XRD and XPS, were adopted to characterize the structural and catalytic features of samples. Results indicated that the impregnation method favors the formation of outer-sphere surface complexes with porous structure as well as well-distributed metallic nanoparticles, while the one-pot synthesis tends to form the inner-sphere surface complexes with relatively smooth appearance and amorphous metals. This difference explains the better activity of catalysts prepared by the impregnation method which can selectively convert benzaldehyde to benzylamine with an excellent yield of 93.7% under the optimal reaction conditions; in contrast, the catalyst prepared by the one-pot synthesis only exhibits a low selectivity near to zero. Furthermore, the gram-scale test catalyzed by the same catalysts exhibits a similar yield of benzylamine in comparison to its smaller scale, which is comparable to the previously reported heterogeneous noble-based catalysts. More surprisingly, the prepared catalysts can be expediently recycled by a magnetic bar and remain the satisfying catalytic activity after reusing up to five times. In conclusion, these developed catalysts enable the synthesis of functional amines with excellent selectivity and carbon balance, proving cost-effective and sustainable access to the wide application of reductive amination.</p></div>","PeriodicalId":12744,"journal":{"name":"Green Energy & Environment","volume":"8 5","pages":"Pages 1358-1370"},"PeriodicalIF":13.3,"publicationDate":"2023-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50175714","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}
