Engineering Pt-based multimetallic nanoalloys could boost electrocatalysis in broad applications, yet it remains challenging terms of its rational design and synthesis a highly diluted alloy with unprecedented Pt atomic utilization. Herein, atomically dispersed anchored on the surface novel RhBi intermetallic nanoplates (RhBi-Pta) is achieved by replacement, which transforms into tensile-strained RhPta (RhBi@RhPta) via electrochemical dealloying. Due to atoms Rh shell, RhBi@RhPta electrocatalyst exhibits remarkably enhanced peak mass activity 32459.1 mA mg–1Pt toward ethanol oxidation reaction (EOR) alkaline electrolyte, while RhBi-Pta nanocrystals show negligible activities. This work provides general strategy for engineering alloys efficient electrocatalysis, based well-defined compounds.

Transition metal selenides (TMSes) with high electrical conductivity, easily regulated morphological structure, and unique electronic structure have been explored as promising electrocatalysts for electrolytic water, while the lower intrinsic electrocatalytic capability has limited their wide application. Herein, we obtained CoSe nanosheet arrays Bi cations incorporation (CoBiSex arrays) driven by spinel oxides. Compared oxides, low electronegativity of Se in CoBiSex leads to a portion Co2+ spin states (t2g6eg1) due covalent interaction between Co Se, which can facilitate charge transfer. Density functional theory (DFT) calculation results further identify redistribution electron density from Co, intensifying adsorption OOH* during water process 140 h robust catalytic performance. This work offers strategy exploring TMSe materials potential applications process.

Abstract Efficient ethanol oxidation reaction (EOR) catalysts with anti‐poisoning ability and high selectivity are in demand for the widespread application of direct fuel cells (DEFCs). Here, PdSnW ternary alloy nanoparticles synthesized by a facile solvothermal method exhibit an enhanced EOR catalytic performance. CO stripping experiment, X‐ray photoelectron spectroscopy situ Fourier transform infrared employed to study correlation between catalyst structure The oxyphilic Sn W not only provide dangling O−H bond, accelerating subsequent adsorbed intermediate species, but also moderate electron state Pd, enhancing adsorption CH 3 2 OH, thus resulting promotion C−C bond cleavage increased C1 selectivity. As consequence, nanoparticle better stability higher mass activity than those Pd/C, PdSn PdW, respectively. This work offers novel insights strategically design highly efficient electrocatalysts oxidation, further clarifies inherent structure‐activity relationship.
