The mobility and accessibility of active sites in Cu-based catalysts significantly hinder the development of efficient Cu-based catalysts for CO<sub>2</sub> electrochemical reduction reaction (CO<sub>2</sub>RR). Herein, a facile and effective strategy is developed to engineer accessible and structural stable Cu sites by incorporating single atomic Cu into the nitrogen cavities of the host graphitic carbon nitride (g-C<sub>3</sub>N<sub>4</sub>) as the active sites for CO<sub>2</sub>-to-CH<sub>4</sub> conversion in CO<sub>2</sub>RR. By regulating the coordination and density of Cu sites in g-C<sub>3</sub>N<sub>4</sub>, an optimal catalyst corresponding to a one Cu atom in one nitrogen cavity reaches the highest CH<sub>4</sub> Faraday efficiency of 49.04% and produces the products with a high CH<sub>4</sub>/C<sub>2</sub>H<sub>4</sub> ratio over 9. This work provides the first experimental study on g-C<sub>3</sub>N<sub>4</sub>-supported single Cu atom catalyst for efficient CH<sub>4</sub> production from CO<sub>2</sub>RR and suggests a principle in designing highly stable and selective high-efficiency Cu-based catalysts for CO<sub>2</sub>RR by engineering Cu active sites in 2D materials with porous crystal structures.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":48779,"journal":{"name":"Nano-Micro Letters","volume":"15 1","pages":""},"PeriodicalIF":26.6,"publicationDate":"2023-10-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10603021/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"50160243","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the understanding on how the salts impact on the Li loss remains unclear. Herein, using the electrolytes with different salts (e.g., lithium hexafluorophosphate (LiPF<sub>6</sub>), lithium difluoro(oxalato)borate (LiDFOB), and lithium bis(fluorosulfonyl)amide (LiFSI)) as examples, we decouple the irreversible Li loss (SEI Li<sup>+</sup> and “dead” Li) during cycling. It is found that the accumulation of both SEI Li<sup>+</sup> and “dead” Li may be responsible to the irreversible Li loss for the Li metal in the electrolyte with LiPF<sub>6</sub> salt. While for the electrolytes with LiDFOB and LiFSI salts, the accumulation of “dead” Li predominates the Li loss. We also demonstrate that lithium nitrate and fluoroethylene carbonate additives could, respectively, function as the “dead” Li and SEI Li<sup>+</sup> inhibitors. Inspired by the above understandings, we propose a universal procedure for the electrolyte design of Li metal batteries (LMBs): (i) decouple and find the main reason for the irreversible Li loss; (ii) add the corresponding electrolyte additive. With such a Li-loss-targeted strategy, the Li reversibility was significantly enhanced in the electrolytes with 1,2-dimethoxyethane, triethyl phosphate, and tetrahydrofuran solvents. Our strategy may broaden the scope of electrolyte design toward practical LMBs. </p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":48779,"journal":{"name":"Nano-Micro Letters","volume":"15 1","pages":""},"PeriodicalIF":26.6,"publicationDate":"2023-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10597960/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49688278","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we describe the construction of biodegradable metal–organic framework based nanobots with chemically driven buoyancy to achieve highly efficient, long-distance, directional vertical motion to “find-and-fetch” target cells. Nanobots surface-functionalized with antibodies against the cell surface marker carcinoembryonic antigen are exploited to impart the nanobots with specific cell targeting capacity to recognize and separate cancer cells. We demonstrate that the self-propelled motility of the nanobots can sufficiently transport the recognized cells autonomously, and the separated cells can be easily collected with a customized glass column, and finally regain their full metabolic potential after the separation. The utilization of nanobots with easy synthetic pathway shows considerable promise in cell recognition, separation, and enrichment. </p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":48779,"journal":{"name":"Nano-Micro Letters","volume":"15 1","pages":""},"PeriodicalIF":26.6,"publicationDate":"2023-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC10597912/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49688277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
