Electrocatalytic urea synthesis from CO and nitrate holds immense promise as a sustainable strategy, but its complicated synthesis steps and controversial C-N coupling mechanism restrict the design of efficient catalysts. Atomically precise metal cluster materials are ideal model catalysts for investigating the C-N coupling issues. Here we synthesize two atomically precise bimetallic clusters, AgPd(PTFE)(TPP) and AgAu(PTFE)(DPPP), both with icosahedral cores and similar ligands.

The electrocatalytic nitrogen reduction reaction (eNRR) is an attractive strategy for the green and distributed production of ammonia (NH); however, it suffers from weak N adsorption and a high energy barrier of hydrogenation. Atomically dispersed metal dual-site catalysts with an optimized electronic structure and exceptional catalytic activity are expected to be competent for knotty hydrogenation reactions including the eNRR. Inspired by the bimetallic FeMo cofactor in biological nitrogenase, herein, an atomically dispersed FeMo dual site anchored in nitrogen-doped carbon is proposed to induce a favorable electronic structure and binding energy.

Article Synopsis
- The study explores using electrodeposited copper (Cu) and tin (Sn) in electrocatalysts to efficiently reduce atmospheric CO and produce valuable products while integrating with renewable energy.
- The research focuses on different configurations of Cu and Sn, finding that a catalyst with Sn over a thin layer of Cu performs best, demonstrating promising durability in initial tests.
- Optimized Sn and Cu-based catalysts yield over 60% organic products, mainly CO, at low energy costs (under 3 V), highlighting the process's economic viability.

The development of Pd-based bimetallic nanoalloys (NAs) with abundant active sites for achieving highly efficient electrocatalysis in alcohol oxidation deserves continuous attention. Herein, we utilized a facile visible-light-assisted liquid-phase method involving adjusting reaction time to generate active sites, successfully synthesizing one-dimensional (1D) PdAg NAs rich in defects. The optimized 1D PdAg NA exhibits remarkable electrochemical activity, stability, and antipoisonous properties in glycerol oxidation reaction (GOR) and ethanol oxidation reaction (EOR), far exceeding pure Pd and commercial Pd/C catalysts.

In the electrocatalytic (EC) degradation process, challenges such as inefficient mass transfer, suboptimal mineralization rates, and limited current efficiency have restricted its broader application. To overcome these obstacles, this study synthesized spherical particle electrodes (FeNi@BC) with superior electrocatalytic performance using a bio-inspired preparation method. A three-dimensional electrocatalytic oxidation system based on FeNi@BC electrode, EC/FeNi@BC, showed excellent degradation efficiency of sulfamethoxazole (SMX), reaching 0.
