Abstract Single‐atom decorating of Pt emerges as a highly effective strategy to boost catalytic properties, which can trigger the most active sites while blocking smallest number atoms. However, rational design and creation high‐density single‐atoms on surface remain huge challenge. Herein, customized synthesis surface‐enriched single‐Bi‐atoms tailored nanorings ( SE‐Bi 1 /Pt NRs ) toward methanol oxidation is reported, guided by density functional theory (DFT) calculations suggesting that...
Abstract Electrochemical ethanol oxidation is crucial to directly convert a biorenewable liquid fuel with high energy density into electrical energy, but it remains an inefficient reaction even the best catalysts. To boost oxidation, developing multimetallic nanoalloy has emerged as one of most effective strategies, yet faces challenge in rational engineering active‐site ensembles at atomic‐level. Herein, starting from typical PtCu nanocrystals, atomic Sn diffusion strategy developed...
The electrochemical coupling of CO2 and NO3– on copper-based catalysts presents a sustainable strategy for urea production while simultaneously addressing wastewater denitrification. However, the inefficient random adsorption copper surface limits interaction key carbon nitrogen intermediates, thereby impeding efficient C–N coupling. In this study, we demonstrate that residual lattice oxygen in oxide-derived nanosheets (OL-Cu) can effectively tune electron distribution, thus activating...
The relationship between the heterogeneous grain structure and mechanical properties is an emerging aspect of effort to expand applications Mg alloy. In this study, heterostructured alloy, comprising elongated fine equiaxed grains, was fabricated through a simple hot-extrusion process with extrusion temperature 320 °C.
