In this context, induction heating has emerged as a promising strategy to enhance catalytic performance in both metal-free carbon catalysts and metal-supported systems. This perspective emphasizes its strong potential, showing that induction heating improves performance not only through localized thermal effects but also through possible non-thermal contributions from alternating current magnetic fields. These fields can influence radical lifetimes, spin states, adsorption–desorption equilibria, and defect reactivity, thereby enabling reaction pathways and selectivities that remain inaccessible under conventional heating. Coupling carbon and supported metal catalysts with induction heating also offers an effective way to mitigate deactivation, as defect sites can act as adsorption centers that, under magnetic field stimulation, promote targeted transformations. Direct evidence for non-thermal contributions to catalytic performance remains scarce, mainly due to the limited availability of operando investigations. Nevertheless, the substantial gains in activity and selectivity observed under induction heating cannot be explained solely by localized thermal effects, suggesting an additional non-thermal influence. These findings point toward new opportunities for designing next-generation catalysts with improved operability and stability. In addition, the combined evidence of localized thermal effects, non-thermal field interactions, and the advantages of carbon-based catalysts shows that the synergy between advanced material design and induction heating provides a powerful pathway for electricity-driven catalysis, with significant implications for decarbonizing the chemical industry and advancing the energy transition.</div></div>","PeriodicalId":100892,"journal":{"name":"Materials Today Catalysis","volume":"12 ","pages":"Article 100134"},"PeriodicalIF":0.0,"publicationDate":"2026-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145738848","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Urea electrosynthesis through C-N coupling offers a promising alternative by utilizing CO<sub>2</sub> and renewable electricity under ambient conditions. However, the high activation barrier of N<sub>2</sub> (N<img>N bond energy: 941 kJ mol<sup>−1</sup>) limits electrosynthesis efficiency. This review highlights the emerging strategy of substituting nitrogen oxide (NO<sub>x</sub>) pollutants (NO and N<sub>2</sub>O) for N<sub>2</sub> as reactive nitrogen sources, which not only circumvents N<sub>2</sub> activation challenges but also enables simultaneous environmental remediation. The fundamental reaction mechanisms involved in co-reduction of NO<sub>x</sub> and CO<sub>2</sub> are systematically outlined and discussed. Subsequently, the review delves into critical aspects of catalyst design encompassing both computational screening approaches and experimental research findings for developing efficient catalytic systems. A significant focus is placed on analyzing the current limitations hindering practical implementation, including low urea yield rates (UYR) as well as low Faradaic efficiency (FE), challenges posed by low reactant concentrations, and economic barriers related to industrial-scale applications. Finally, the review presents future perspectives to overcome these hurdles, highlighting promising directions such as the development of more efficient computational screening tools, diversification of feedstock sources, and innovative reactor and catalyst design strategies. This co-reduction pathway represents a potentially sustainable and carbon-neutral route for urea production, utilizing greenhouse gases and nitrogen pollutes as direct feedstocks.</div></div>","PeriodicalId":100892,"journal":{"name":"Materials Today Catalysis","volume":"11 ","pages":"Article 100128"},"PeriodicalIF":0.0,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145474390","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
