However, the requirement of highly pure H2 for re-hydrogenation limits its wide application. Here, amorphous Al2O3 shells (10 nm) were deposited on the surface of highly active hydrogen storage material particles (MgH2-ZrTi) by atomic layer deposition to obtain MgH2-ZrTi@Al2O3, which have been demonstrated to be air stable with selective adsorption of H2 under a hydrogen atmosphere with different impurities (CH4, O2, N2, and CO2). About 4.79 wt% H2 was adsorbed by MgH2-ZrTi@10nmAl2O3 at 75 °C under 10%CH4 + 90%H2 atmosphere within 3 h with no kinetic or density decay after 5 cycles (~ 100% capacity retention). Furthermore, about 4 wt% of H2 was absorbed by MgH2-ZrTi@10nmAl2O3 under 0.1%O2 + 0.4%N2 + 99.5%H2 and 0.1%CO2 + 0.4%N2 + 99.5%H2 atmospheres at 100 °C within 0.5 h, respectively, demonstrating the selective hydrogen absorption of MgH2-ZrTi@10nmAl2O3 in both oxygen-containing and carbon dioxide-containing atmospheres hydrogen atmosphere. The absorption and desorption curves of MgH2-ZrTi@10nmAl2O3 with and without absorption in pure hydrogen and then in 21%O2 + 79%N2 for 1 h were found to overlap, further confirming the successful shielding effect of Al2O3 shells against O2 and N2. The MgH2-ZrTi@10nmAl2O3 has been demonstrated to be air stable and have excellent selective hydrogen absorption performance under the atmosphere with CH4, O2, N2, and CO2.","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"58 1","pages":"78"},"PeriodicalIF":26.6,"publicationDate":"2025-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145351729","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we suggest an effective approach to control the micropore structure of silicon oxide (SiO<sub><i>x</i></sub>)/artificial graphite (AG) composite electrodes using a perforated current collector. The electrode features a unique pore structure, where alternating high-porosity domains and low-porosity domains markedly reduce overall electrode resistance, leading to a 20% improvement in rate capability at a 5C-rate discharge condition. Using microstructure-resolved modeling and simulations, we demonstrate that the patterned micropore structure enhances lithium-ion transport, mitigating the electrolyte concentration gradient of lithium-ion. Additionally, perforating current collector with a chemical etching process increases the number of hydrogen bonding sites and enlarges the interface with the SiO<sub><i>x</i></sub>/AG composite electrode, significantly improving adhesion strength. This, in turn, suppresses mechanical degradation and leads to a 50% higher capacity retention. Thus, regularly arranged micropore structure enabled by the perforated current collector successfully improves both rate capability and cycle life in SiO<sub><i>x</i></sub>/AG composite electrodes, providing valuable insights into electrode engineering.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":714,"journal":{"name":"Nano-Micro Letters","volume":"18 1","pages":""},"PeriodicalIF":36.3,"publicationDate":"2025-10-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s40820-025-01929-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145246378","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}

Notably, by critically analyzing metallic cobalt, cobalt alloys, cobalt compounds, cobalt single atom and molecular catalyst configurations, we firstly establish correlations between atomic-scale structural features and catalytic performance in a coordination environment perspective for NO<sub>3</sub>RR, including the dynamic reconstruction during operation and its impact on active site. Synergizing experimental breakthroughs with computational modeling, we decode mechanisms underlying competitive hydrogen evolution suppression, intermediate adsorption-energy optimization, and durability enhancement in complex aqueous environments. The development of cobalt-based catalysts was summarized and prospected, and the emerging opportunities of machine learning in accelerating the research and development of high-performance catalysts and the configuration of series reactors for scalable nitrate-to-ammonia systems were also introduced.
