To optimize this process, designing catalysts for selective ammonia-to-nitrite electrooxidation with enhanced electron transfer and high current density is practically important. Nickel-based materials are effective AOR catalysts, particularly through the self-oxidation reconstruction into NiOOH. However, pristine NiOOH typically yields multiple products and catalyzes the competing oxygen evolution reaction (OER) within a similar potential range, hindering the high selectivity required for valuable AOR products. Herein, we report a Cu-doped nickel sulfide catalyst (Cu-NiS<sub>2</sub>) with an optimized electronic configuration, which undergoes surface reconstruction to form sulfur oxyanion-coordinated Cu-NiOOH-SO<sub><em>x</em></sub> at ∼1.60 <em>V</em> vs. RHE. The incorporation of Cu facilitates electron transfer in Ni, while the SO<sub><em>x</em></sub> anions refines the coordination environment of Ni, modulating its electronic structure and enabling balanced adsorption of nitrogen-containing intermediates. This synergistic effect enhances both AOR activity and selectivity. As a result, the catalyst achieves an exceptional AOR current density of 104.8 mA cm<sup>−2</sup> at 1.65 <em>V</em>, along with an ammonia conversion efficiency of 90.3 % over 8-h and a NO<sub>2</sub><sup>−</sup> selectivity of 95.4 %.

In this context, electrolyzers have become a focal point of global research, as they facilitate the production of green hydrogen. Among electrolyzers, solid oxide electrolyzers are one of the most widely researched due to their high efficiency and their variability in terms of fuels and operation as fuel cells. However, due to the use of critical materials in combined with a relatively short operational lifespan, the development of recycling strategies is becoming increasingly crucial if these electrolyzers are to become a sustainable option for green hydrogen production. This study proposes the first comprehensive recycling scheme for solid oxide electrolyzer stacks. Data on the materials used by electrolyzer manufacturers from around the world was compiled and compared. Based on these materials, published recycling approaches from dismantling, mechanical recycling and metallurgy were combined with additional studies to develop a holistic recycling process aimed at recovering critical raw materials. Options for closed-loop and open-loop reuse were considered and existing gaps and challenges were identified. The current status of recycling solid oxide electrolyzer stacks demonstrates that the principle is feasible and that a significant proportion of the materials used can already be separated and recovered. However, existing gaps, such as the separation of the nickel mesh from interconnects and the separation of various oxygen ion conductors, currently result in materials being downcycled or recycled in an open loop.</div></div>","PeriodicalId":22097,"journal":{"name":"Sustainable Materials and Technologies","volume":"45 ","pages":"Article e01435"},"PeriodicalIF":8.6,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143924245","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A simple yet effective ink formulation composed exclusively of soluble polyimide (sPI) and solvents is presented. Upon extrusion, the ink undergoes rapid gelation and solidification via VIPS triggered by ambient moisture, followed by solvent exchange in liquid water to form sPI filaments with dense skins and microporous cores. By programmably adjusting nozzle trajectories, the macroscopic features of the filaments can be precisely controlled, enabling the fabrication of 3D sPI dielectrics with a porosity of up to 87 %. These materials exhibit an ultralow permittivity of 1.32 and a loss tangent of 0.005 at 1 MHz, surpassing the performance of many existing dielectrics. The 3D dielectrics are applied in the fabrication of coplanar waveguide antennas and thermal management systems, demonstrating their potential for high-frequency communication and advanced electronics. Furthermore, the 3D sPI prints can be fully recycled by dissolving the products in solvents and reprocessing them into new ultralow-permittivity dielectrics, offering a sustainable and low-carbon manufacturing strategy for the microelectronics industry.
