The construction of high-activity and low-cost electrocatalysts is critical for efficient hydrogen production by water electrolysis. Herein, we developed an advanced electrocatalyst anchoring well-dispersed Ir nanoparticles on nickel metal-organic framework (MOF) Ni-NDC (NDC: 2,6-naphthalenedicarboxylic) nanosheets. Benefiting from the strong synergy between MOF through interfacial Ni-O-Ir bonds, synthesized Ir@Ni-NDC showed exceptional electrocatalytic performance evolution reaction (HER), oxygen (OER) overall splitting in a wide pH range, superior to commercial benchmarks most reported electrocatalysts. Theoretical calculations revealed that charge redistribution bridge induced optimization H2 O, OH* H* adsorption, thus leading accelerated electrochemical kinetics HER OER. This work provides new clue exploit bifunctional pH-universal splitting.

Abstract The development of a methodology for synthesizing value‐added urea (CO(NH 2 ) via renewable electricity‐driven C−N coupling reaction under mild conditions is highly anticipated. However, the complex catalytic active sites that act on carbon and nitrogen species make mechanism unclear, resulting in low efficiency from co‐reduction dioxide (CO nitrate (NO 3 − ). Herein, we propose novel tandem catalyst Mo‐PCN‐222(Co), which Mo serve to facilitate reduction *NH intermediate, while Co enhance CO carbonic oxide (CO), thus synergistically promoting coupling. synthesized Mo‐PCN‐222(Co) exhibited noteworthy yield rate 844.11 mg h −1 g , alongside corresponding Faradaic 33.90 % at −0.4 V vs. reversible hydrogen electrode (RHE). By combining situ spectroscopic techniques with density functional theory calculations, demonstrate efficient attributed system *CO intermediates produced by stabilize formation *CONH intermediate. This study provides an effective avenue design synthesis catalysts electrocatalytic synthesis.
