Abstract Urea electrosynthesis from co–electrolysis of NO 3 − and CO 2 (UENC) offers a promising technology for achieving sustainable efficient urea production. Herein, diatomic alloy catalyst (CuPd 1 Rh –DAA), with mutually isolated Pd atoms alloyed on Cu substrate, is theoretically designed experimentally confirmed to be highly active selective UENC catalyst. Combining theoretical computations operando spectroscopic characterizations reveals the synergistic effect –Cu sites promote via tandem catalysis mechanism, where site triggers early C–N coupling promotes *CO –to–*CO NH steps, while facilitates subsequent protonation step *COOHNH toward formation. Impressively, CuPd –DAA assembled in flow cell presents highest Faradaic efficiency 72.1% yield rate 53.2 mmol h −1 g cat at −0.5 V versus RHE, representing nearly performance among all reported catalysts.

Electrocatalytic CO2 reduction into high-value multicarbon products offers a sustainable approach to closing the anthropogenic carbon cycle and contributing neutrality, particularly when renewable electricity is used power reaction. However, lack of efficient durable electrocatalysts with high selectivity for multicarbons severely hinders practical application this promising technology. Herein, nanoporous defective Au1Cu single-atom alloy (De-Au1Cu SAA) catalyst developed through facile low-temperature thermal in hydrogen subsequent dealloying process, which shows toward ethylene (C2H4), Faradaic efficiency 52% at current density 252 mA cm–2 under potential −1.1 V versus reversible electrode (RHE). In situ spectroscopy measurements functional theory (DFT) calculations reveal that C2H4 product results from synergistic effect between Au single atoms Cu sites on surface catalysts, where promote *CO generation defects stabilize key intermediate *OCCO, altogether enhances C–C coupling kinetics. This work provides important insights design electrochemical products.

Abstract Electrochemical oxidation of small molecules shows great promise to substitute oxygen evolution reaction (OER) or hydrogen (HOR) enhance kinetics and reduce energy consumption, as well produce high‐valued chemicals serve fuels. For these reactions, high‐valence metal sites generated at oxidative potentials are typically considered active trigger the process molecules. Isolated atom site catalysts (IASCs) have been developed an ideal system precisely regulate state coordination environment single‐metal centers, thus optimize their catalytic property. The isolated in IASCs inherently possess a positive state, can be more readily homogeneous under than nanoparticle counterparts. Meanwhile, merely centers but lack ensemble sites, which alter adsorption configurations compared with counterparts, induce various pathways mechanisms change product selectivity. More importantly, construction is discovered limit d‐electron back donation CO 2p * orbital overly strong on resolve poisoning problems most electro‐oxidation reactions improve stability. Based advantages fields electrochemical molecules, this review summarizes recent developments advancements focusing anodic HOR fuel cells OER electrolytic alternative such formic acid/methanol/ethanol/glycerol/urea/5‐hydroxymethylfurfural (HMF) key reactions. merits different decoding structure–activity relationships specifically discussed guide precise design structural regulation from perspective comprehensive mechanism. Finally, future prospects challenges put forward, aiming motivate application possibilities for diverse functional IASCs.

Abstract Recently, dual‐atom alloy (DAA, also named diatomic alloy) catalysts with active metal dimers supported by a less host have attracted considerable interest owing to their distinctive geometric and electrical configurations. Despite developing many ways for synthesizing DAA catalysts, most contemporary methods depend on high‐temperature pyrolysis, costly apparatus, intricate procedures. This study presents, the first time, one‐step laser solid‐phase synthesis of (PtRu) 1 Co DAAs low‐defect graphene support via ultraviolet (UV) irradiation mixed precursors ZIF‐67@PBI composite support. The special structure enhances catalytic performance hydrogen evolution reaction (HER) in an alkaline solution. An overpotential 27 mV is reached at current density ‐10 mA cm⁻ 2 . mass activity 200 19.6 times more than that commercial Pt/C catalyst. Moreover, sustained stability over 100 h ‐200 cm −2 results demonstrated potential as viable method precise controlling defect formations nanoparticles carbon technique rapid cost‐effective opens up new avenue toward large‐scale catalysts.
