Engineering Bimetallic Copper‐Tin Based Core‐Shell Alloy@Oxide Nanowire as Efficient Catalyst for Electrochemical CO2 Reduction
Pursuing both high effective and selective electrocatalysts is significant for efficient and low‐cost electrochemical carbon dioxide (CO2) reduction. Here, we design a novel bimetallic alloy/oxide nanowire catalyst with core‐shell configuration. A typical CuSn alloy core provides high electrical conductivity while the amorphous Cu doped SnO2 shell guarantees the catalytic activity and selectivity for CO2 reduction process. Computational studies further elucidate the important role of Cu doped SnO2 layer in the electrocatalytic selectivity for formate and the restraint of hydrogen production. Benefited from the well‐designed components and hierarchical configuration, the as‐prepared electrocatalyst displays a partial current density of 30 mA cm−2 with a Faradaic efficiency of 78 % at −0.9 V vs. reversible hydrogen electrode (RHE) for formate. This work provides a new pathway to design advanced electrocatalyst for CO2 electrochemical reduction.

Rigid anchoring of highly crystallized and uniformly dispersed Pd nanocrystals on carbon fibers for ambient electrocatalytic reduction of nitrogen to ammonia
Developing efficient and stable electrocatalysts for ammonia synthesis via the nitrogen reduction reaction (NRR) is essential for the Earth's nitrogen cycle. Herein, a palladium nanocrystals anchored carbon fibers (PdNCs@CNFs) composite was prepared via electrospinning and carbonization processes. X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) characterization studies show that the as-prepared Pd grains are homogeneously anchored on the outer/inner section of the carbon nanofibers. Benefiting from the sufficient exposure and stress effect of active sites, the resultant PdNCs@CNFs achieves a high Faraday efficiency of ∼14.8% with a current density of 0.028 mA cm−2 at −0.2 V vs. reversible hydrogen electrode (RHE) in 0.1 M Na2SO4 solution, surpassing those of many catalysts previously reported. Density functional theory (DFT) calculations reveal that the rationality of the distal associative mechanism on PdNCs@CNFs and Pd nanocrystals on the surface of PdNCs@CNFs is more favorable for nitrogen (N2) molecule adsorption and polarization.
