In this study, a series of Al-based core–shell nanofiber catalysts were synthesized and employed for the catalytic hydrolysis of COS. The Al2O3@Cu-Ce catalyst demonstrated a 100% COS conversion efficiency at a gas hourly space velocity of 15 000 h−1 at 70°C. The interaction of Cu and Ce can enhance their dispersion and facilitate the formation of micropores. The formation of Cu2Al4O7 and CeAlO3 resulted in a reduction in the number of micropores and effective active components on the catalyst surface. The primary catalytic roles were played by Cu2+ and Ce3+. The high content of adsorbed state oxygen Oβ and suitable water resistance resulted in enhanced hydrolysis performance. The Al2O3 shell layer is capable of effectively protecting the Cu and Ce components from being covered and consumed, thereby prolonging the lifetime of the catalyst. The addition of Cu resulted in alterations to both the weakly and moderately basic sites, whereas the addition of Ce primarily affected the weakly basic sites. The formation of Cu-O-Ce increased the percentage of CuO in the Cu fraction, thereby enhancing the COS removal performance. There is a competitive adsorption relationship between COS and H2S on the CuO (002) surface. COS, H2O, and H2S compete for adsorption on the Ov-CeO2 (111) surface. Ov-CeO2 (111) promotes the dissociation of H2O and the generation of -SH groups. The hydrolysis process of COS occurs in steps on CuO (002) and Ov-CeO2 (111).","PeriodicalId":100387,"journal":{"name":"EcoEnergy","volume":"3 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ece2.70011","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145128973","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}

However, traditional PSME methods encounter challenges such as prolonged solvothermal incubation and difficulties in introducing secondary metal elements. Thus, developing a rapid, sustainable, and scaled-up PSME approach for MOFs is essential. Herein, we present a mechanochemical-assisted defect engineering strategy that accelerates the PSME process (mechano-PSME). Characterization techniques demonstrate that this strategy swiftly overcomes the energy barriers of the parent MOFs, resulting in the formation of an abundance of defects. This creates an optimal environment for incorporating heterometallics, thus facilitating rapid, batch PSME of MOFs. The experimental results clearly validate the effectiveness of mechano-PSME in producing bimetallic Zr/Hf-based UiO-66, a process challenging to achieve under solvothermal conditions. Additionally, the Zr/Hf-based UiO-66 exhibits improved acidic functionality and exceptional catalytic efficiency in the esterification of levulinic acid.

Although solar-powered CP systems have emerged to replace conventional systems, the available technical routes are far from perfect: the efficiencies of semiconductor-based small photoelectrochemical devices are still low, and ICCP systems driven by photovoltaic (PV) cells are often large in size and high in cost. Herein, a portable CP device (30 × 30 × 20 cm3 and 5.1 kg) with a modular design has been constructed, the fully functioning of which is solely powered by a PV cell without any external electricity input. A real-time “monitoring-feedback-adjustment” mechanism was modulated by a cost-effective and multifunctional microprocessor to precisely maintain the metal potential within the protective potential range. Moreover, a lab-made noble-metal-free auxiliary anode composed of porous Ni foam coated with NiMo alloy was first introduced to the PV-driven ICCP system, which accelerated the water oxidation kinetics compared to various commercial anodes and elevated the overall energy efficiency. Consequently, the as-built SMPCPD was capable of providing continuous CP to three types of representative metals in natural seawater under outdoor sunlight illumination conditions. These findings represent a variable pathway to achieve CP of underwater and underground steel structures with zero carbon emission, no environmental toxicity, intelligent control, high-energy efficiency, and flexibility.","PeriodicalId":100387,"journal":{"name":"EcoEnergy","volume":"3 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ece2.70009","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145129189","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 use of traditional fossil fuels has put immense pressure on the environment and brought about challenges related to energy security and climate change. Therefore, researching alternative energy sources and green catalytic technologies has become key to solving these problems. Among various sustainable energy technologies, reactions such as hydrogen production, carbon dioxide reduction, nitrogen reduction, and oxygen reduction play a crucial role in the conversion and storage of clean energy. However, traditional catalysts face challenges in efficiency, selectivity, and stability, which limit their commercialization process. Single-atom catalysts (SACs), as a new type of catalyst, have shown excellent catalytic performance due to their high surface area and precise control of active sites, significantly reducing catalytic costs. SACs have performed well in water splitting, carbon dioxide reduction, nitrogen reduction, and oxygen reduction reactions, but their application still faces challenges such as synthesis complexity, stability issues, and a deep understanding of catalytic mechanisms. This article explores the key role of SACs in sustainable energy conversion, analyzes their application in various energy conversion reactions, evaluates performance enhancement strategies, and discusses the challenges they face and their future prospects. Through a comprehensive analysis, this article aims to provide an in-depth understanding of the application of SACs in the energy field, promoting technological advancement and commercial application in this area.","PeriodicalId":100387,"journal":{"name":"EcoEnergy","volume":"3 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ece2.70008","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145129110","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 this research, iron oxides with varied surface area and diverse phases were synthesized from the precursor of hydrous ferric oxide, including α-Fe2O3, γ-Fe2O3, and Fe3O4. The bulk and surface properties of these catalysts were characterized by XRD, BET, TG, IR, magnetic analysis, hydrogen adsorption, and 57Fe-Mössbauer spectrum. It was suggested that ortho–para H2 conversion is linearly correlated with the specific surface area of α-Fe2O3 which governs the residual magnetic properties as well as the adsorption capacity of molecular H2 on the catalysts, and a nondissociation mechanism of ortho–para H2 conversion was revealed at cryogenic temperature. The hydrate that contributed to the surface area of iron oxides shows a negative effect on the ortho–para H2 conversion. Moreover, by estimating the reaction rate based on the per surface area of iron oxides, the Fe(III) exposed on surfaces exhibited a superior activity irrespective of the bulk magnetism of iron oxides, and the intrinsic activity of iron oxides for ortho–para H2 conversion was found to follow a trend similar to that of α-Fe2O3 ≈ γ-Fe2O3 > Fe3O4. The findings of this study provide valuable insights for the subsequent research on the mechanism of ortho–para H2 conversion and the design of high-performance hydrogen liquefaction catalysts.","PeriodicalId":100387,"journal":{"name":"EcoEnergy","volume":"3 3","pages":""},"PeriodicalIF":0.0,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/ece2.70004","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145129198","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 homojuction consisted of low Ti doping nanorods grown on high Ti doping nanobowl arrays, leading to the formation of a broad built-in electric field, significantly enhancing the charge separation and transfer within the bulk.
