Among these, electrocatalytic carbon dioxide reduction (ECR), electrocatalytic ammonia synthesis (EAS), and particularly electrocatalytic urea synthesis (EUS) offer promising strategies for green carbon–nitrogen conversion. EUS stands out by co-reducing CO<sub>2</sub> and nitrogen sources (e.g., N<sub>2</sub>, NO, NO<sub>2</sub><sup>−</sup>, NO<sub>3</sub><sup>−</sup>) to enable C–N bond formation, presenting unique opportunities for resource efficiency and emissions reduction. However, its practical implementation is limited by insufficient catalytic activity, selectivity, and durability; incomplete understanding of C–N coupling pathways; and competition from side reactions. Metal–organic framework (MOF)-based materials have emerged as versatile platforms for electrocatalysis owing to their tunable metal nodes and ligand chemistry, multifunctional active sites, and hierarchically porous architectures that afford efficient mass transport. Accordingly, MOF-based platforms are poised to lower the intrinsic C–N coupling barrier, coordinate dual-substrate delivery and co-adsorption, suppress parasitic hydrogen evolution reaction (HER), and improve charge transport and durability in EUS. This review categorizes MOF functionalization strategies for active site design and microenvironment modulation. It then evaluates representative advances with MOF-based materials in ECR, EAS, and EUS, with a particular focus on elucidating structure–mechanism–performance correlations. Drawing on insights from ECR and EAS, we propose transferable design principles to guide the rational development of MOF-based systems for efficient EUS. Finally, we highlight persistent challenges and outline future research directions to advance cross-reaction design strategies and accelerate the practical deployment of MOF-based electrocatalysts.</div></div>","PeriodicalId":7283,"journal":{"name":"Advanced Powder Materials","volume":"5 3","pages":"Article 100370"},"PeriodicalIF":0.0,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145578464","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}

Herein, we propose an etching-assisted strain engineering strategy to deliberately trigger lattice distortions and regulate lattice expansion and contraction in cobalt sulfide heterostructures. We demonstrate that the sequence of processing steps is critical: an etching-first-sulfurization-later approach (Route 1) preferentially induces tensile strain and lattice expansion, whereas a sulfurization-first-etching-later (Route 2) pathway favors compressive strain and lattice contraction. Compared to the strain-free cobalt sulfide (C-0), the optimal sample (C-24) achieves a comparable coexistence of local lattice expansion and contraction via Route 1. This coexistence expedites localized lattice perturbations, enriches lattice distortion-related sulfur vacancies, and intensifies multiphase heterointerfaces, collectively boosting the dielectric polarization response. Consequently, this elaborate strategy enables an effective absorption bandwidth of 5.45 GHz with excellent polarization behavior, which are 1.83-fold and 1.93-fold improvement over C-0, respectively.
