Summary: In this study, uniform Ag@AgP2@Ni-CoP@C core-shell nanowires have been synthesized using a template-engaged strategy. The merging of conductive Ag core with active AgP2 and porous carbon-coated Ni-doped CoP shells favors the mass and electron transfers, effectively lowering the activation energy toward the reduction of N2 to NH3. The titled catalyst achieved a high NH3 yield of 16.84 μg h-1 mg-1 cat. at -0.4V (vs. RHE) and a high Faradaic efficiency of 21.7% at -0.3V vs. RHE, as well as high electrochemical and structure stability.

Summary: The nitrogen reduction reaction (NRR) activity of RuO2 and metallic Ru catalysts was studied in this research to explore the role of oxides and metallic dual active sites. It was found that ruthenium oxide nanoparticles exhibited higher ammonia production rate and Faradaic efficiency compared to Ru black due to the formation of oxygen vacancies on the RuO2 surface, which provided a facile adsorption site for N2 in addition to the Ru4+ active site and promoted proton supply from the metal hydride site.

Summary: Modifying the structures of metal-N-C single-atom catalysts to enhance their catalytic activities is challenging but desirable. The introduction of Ru to create RuFe-N-C or RuCo-N-C double-atom catalysts (DACs) can significantly improve the bifunctional ORR/OER activities, surpassing the individual Fe(Co)-N-C and Ru-N-C. The synergistic effect in RuM-N-C DACs is attributed to the combined optimized metal atoms, which alter the charge density and d-band center, affecting the adsorption energies and catalytic activity of intermediates. The synthesis of RuFe-N-C using a bimetal MOF precursor demonstrates exceptional ORR/OER activities, outperforming Fe-N-C, Ru-N-C, and even commercial Pt/C-RuO2.

Summary: This study presents a facile procedure to synthesize a series of well-structured, symmetry-breaking zinc metal-organic framework (Zn-MOF) catalysts for nitrogen reduction. The optimized coordination microenvironment regulated by symmetry-breaking leads to the best performance of the Zn-N2S2-MOF catalyst in nitrogen reduction reaction (NRR). X-ray absorption near-edge structure analysis reveals that symmetry-breaking distorts the coordination environment and promotes the formation of low-valence Zn delta+ species, which facilitates N2 adsorption/activation. Theoretical calculations support that low-valence Zn delta+ effectively lowers the reaction barrier and enhances the NRR activity.
