However, it is challenging to achieve a metal–nitrogen–carbon (M–N–C) catalyst that exhibits high resistance to corrosive Cl^– in seawater-based electrolytes and possesses a strengthened binding affinity with O₂, which enables catalysts with an optimized oxygen reduction reaction (ORR) and enhances the applicability of S-ZABs. Herein, we propose a combined wet chemistry-pyrolysis strategy to obtain atomically dispersed Fe-decorated nitrogen-doped mesoporous carbon spheres (N-MCS-Fe-900). Benefiting from the capacity of the Fe decorations to form the edge-hosted aerophilic FeN₄-O₂ sites at the optimized three-phase interface, N-MCS-Fe-900 affords the enhanced resistance of the active Fe sites to corrosive Cl^–, as well as improved interaction with O₂, thereby facilitating the ORR process. As expected, the N-MCS-Fe-900 delivers high half wave potential of 0.90 V and kinetic current density of 18.61 mA cm⁻² at 0.85 V in seawater-based 0.1 M KOH. More importantly, the S-ZABs equipped with N-MCS-Fe-900 exhibited long-term stability under a high current density for over 140 h without voltage decay. Theoretical calculations and electrochemical performance evaluations collectively revealed the superior catalytic efficacy and genesis of this activity in N-MCS-Fe-900, which features edge-hosted FeN₄-O₂ sites at the stable three-phase interface in seawater electrolytes. This study provides new insights for the advancement of ORR catalysts in sustainable energy conversion technologies for seawater-based electrolytes.</div></div>","PeriodicalId":100595,"journal":{"name":"Green Carbon","volume":"3 1","pages":"Pages 1-10"},"PeriodicalIF":0.0,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143724850","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}

The MLA yield from glucose using the hierarchical Sn-MFI zeolite was almost twice as high as that using the conventional microporous Sn-MFI zeolite. This superior catalytic performance was attributed to the reduced diffusion limitation of glucose within the hierarchical Sn-MFI catalyst, which possessed significant intercrystalline mesoporosity. Additionally, the hierarchical Sn-MFI catalyst was recycled for five reaction runs of the one-pot conversion of glucose without an obvious loss of activity, indicating excellent stability and reusability and broadening the scope of carbohydrates used to obtain MLA.</div></div>","PeriodicalId":100595,"journal":{"name":"Green Carbon","volume":"2 4","pages":"Pages 383-392"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143098286","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}

In addition, doping CoFe₂O₄ with varying amounts of La further improved its performance. The highest hydrogen yield (393 mL/g) was observed for CoFe₂O₄ doped with 10% by mass of La. The characterization results indicated that La not only facilitated the formation of oxygen vacancies but also accelerated lattice oxygen transfer. Furthermore, an optimized La doping level was found to boost the crystallinity of the oxygen carrier, leading to improved cycling performance.

NGH constitutes the largest hydrocarbon resource on Earth, representing a reservoir of sustainable fuel owing to the possibility of a so-called CO₂–CH₄ replacement process. If CO₂ is injected into NGH sediments, CH₄ is released and CO₂ hydrate formed. The extraction of gas from NGH, combined with carbon capture, presents significant potential advantages in the energy infrastructure and various economic and political contexts, aligning with future green policies. This study contributes to the advancement of knowledge by reviewing the findings of a three-year Italian research project focused on methane recovery and carbon dioxide disposal in NGH. The consortium comprises seven multidisciplinary Italian partners. This study introduces a novel process wherein the CO₂–CH₄ replacement process is integrated with methane purification and CO₂ recirculation, which has been experimentally tested and represents a new advancement in gas hydrate science. Experimental tests at the microscopic and macroscopic levels showed that the efficiency of the process strongly depends on the mutual influence of the properties of water, sediment, and the involved gaseous species. Energy evaluations show that the ratio between the energy spent to complete an entire cycle of replacement and recirculation over the stored energy in the recovered methane is 17%, resulting in a beneficial energy balance, while economic analysis shows that the transition could generate—even in the short term—large high-impact cash-out.</div></div>","PeriodicalId":100595,"journal":{"name":"Green Carbon","volume":"2 4","pages":"Pages 351-365"},"PeriodicalIF":0.0,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143098284","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}
