Abstract Structure and defect control are widely accepted effective strategies to manipulate the activity stability of catalysts. On a freestanding hierarchically porous carbon microstructure, tuning oxygen vacancy in embedded hollow cobaltosic oxide (Co 3 O 4 ) nanoparticles is demonstrated through regulation nanoscale Kirkendall effect. Starting with cobalt nanoparticles, concentration oxygen‐vacancy can vary degree oxidation, thus regulating number active sites catalytic performances. The...
Abstract Core/shell nanocatalysts are a class of promising materials, which achieve the enhanced catalytic activities through synergy between ligand effect and strain effect. However, it has been challenging to disentangle contributions from two effects, hinders rational design superior core/shell nanocatalysts.

High-entropy alloys (HEAs) are attracting intensive attention due to their broad compositional tunability and interesting catalytic properties. However, precisely shaping the HEAs into suprathin low-dimensional nanostructures for achieving diverse applications remains an enormous challenge owing intrinsic thermodynamic instability. Herein we propose a new general low-temperature method incorporating up eight metallic elements one single-phase subnanometer ribbon achieve thinnest HEA metal...
We used entropy engineering to design a series of CoFe2O4-type spinels. Through microstructural characterization, electrochemical measurements, and X-ray photoelectron spectroscopy, we demonstrated that the entropy-stabilized oxide (Co0.2Mn0.2Ni0.2Fe0.2Zn0.2)Fe2O4 has single-phase spinel structure exhibits both efficient stable catalytic oxygen evolution. This is attributable disordered occupation multivalent cations, which induces severe lattice distortion increases configurational entropy,...
The electrosynthesis of high-value-added multicarbon compounds coupled with hydrogen production is an efficient way to achieve carbon neutrality; however, the lack effective bifunctional catalysts in largely hinders its development.

Abstract A crucial issue restricting the application of direct alcohol fuel cells (DAFCs) is low activity Pt‐based electrocatalysts for oxidation reaction caused by intermediate (CO*) poisoning. Herein, a new strategy demonstrated making class sub‐monolayer YO x /MoO ‐surface co‐decorated ultrathin platinum nanowires (YO –Pt NWs) to effectively eliminate CO poisoning enhancing methanol electrocatalysis. By adjusting amounts and MoO decorated on surface Pt NWs, optimized 22% NWs achieve high...

Rationally designing the core/shell architecture of Pt-based electrocatalysts has been demonstrated as an effective way to induce a surface strain effect for promoting sluggish kinetics oxygen reduction reaction (ORR) at cathode fuel cells.
