Abstract Metal–organic frameworks (MOFs) have emerged as promising materials in the realm of electrocatalysis due to their high surface area, tunable porosity, and versatile chemical functionality. However, practical application has been hampered by inherent limitations such low electrical conductivity a limited number active metal sites. Researchers addressed these challenges through various strategies, including enhancing incorporating conductive nanoparticles, modifying structure composition MOFs replacing nodes functionalizing linkers, preparing catalysts thermal processes decarburization conversion into oxides, phosphides (MPs), sulfides (MSs). This review provided comprehensive summary strategies that were employed enhance electroactivity for improved electrocatalytic performance recent years. It also explored future directions potential innovations design synthesis MOF‐based electrocatalysts, offering valuable insights advancing sustainable energy technologies.

Abstract The excess nitrate (NO 3 − ) in water mainly comes from agricultural fertilization and industrial wastewater, which breaks the nitrogen balance poses a serious threat to environment human health. Driven by renewable energy, electrocatalytic NO reduction ammonia (NH (ENO RA) is an environmentally friendly sustainable technology. Due its special structure, copper (Cu) currently one of best catalysts for ENO RA, but reaction mechanism structure–activity relationships are still not clear enough. In‐situ characterization powerful tool gain insight into process. This review introduces several types in‐situ techniques such as XAS, FTIR DEMS, summarizes five pathways converting *NO key intermediate NH during RA on Cu‐based catalysts. research progress electrocatalysts recent years sorted out aspects composition catalytic mechanisms discussed with help technologies. would be provide reference methods exploring design RA.

Photocatalytic nitrogen fixation is one of the important pathways for green and sustainable ammonia synthesis, but extremely high bonding energy N≡N triple bond makes it difficult conventional photocatalysts to directly activate hydrogenate. Given this, we covalently grafted phenanthroline unit onto graphitic carbon nitride nanosheets (CN) by simple thermal oxidation method complexed with transition metal Fe3+ ions obtain stable dispersed Fe active sites, which can significantly improve photocatalytic activity. The Fe(III)-4-P-CN photocatalyst morphology consists porous lamellar structures internally connected nanowires. special catalysts gives them excellent performance, an average NH3 yield 492.9 μmol g–1 h–1, 6.5 times higher than that pristine CN, as well better cycling stability. Comprehensive experiments density-functional theory results show more favorable CN *N2 activation, effectively lowering reaction barrier. Moreover, other byproducts (such nitrate H2O2) are also produced during process, provides a new way nitrogen-fixing achieve multifunctional applications.
