In situ/operando characterization techniques are powerful to provide fundamental information about molecular structure–activity/selectivity relationships for various catalytic systems under controlled condition. However, the lack of model catalyst, as major obstacle deeper understanding on nature active sites and reaction mechanisms, hinders further advancements in catalysis. Fortunately, rapid development single-atom catalysts (SACs) offers us new opportunities capturing intermediates,...
Abstract The oxygen evolution reaction (OER) is a key process involved in energy and environment‐related technologies. An ideal OER electrocatalyst should show high exposure of active sites optimal adsorption energies oxygenated species. However, earth‐abundant transition‐metal‐based electrocatalysts still operate with sluggish kinetics. Here, cation‐exchange route reported to fabricate cobalt‐vanadium‐iron (oxy)hydroxide (CoV‐Fe 0.28 ) nanosheets tunable binding for the intermediates....
Driven by the persisting poor understanding of sluggish kinetics hydrogen evolution reaction (HER) on Pt in alkaline media, a direct correlation interfacial water structure and activity is still yet to be established. Herein, using Pt-Ni nanoparticles we first demonstrate strong dependence proton donor HER pH.

In electrochemical ethanol oxidation reactions (EOR) catalyzed by Pt metal nanoparticles through a C2 route, the dissociation of C-C bond in molecule can be limiting factor. Complete EOR processes producing CO2 were always exemplified oxidative dehydrogenation C1 intermediates, reaction route with less energy utilization efficiency.

Abstract Multi‐metallic catalysts with specific structures play a crucial role in enhancing the selectivity and activity of chemical reactions. However, challenges such as unfavorable alcohol adsorption on catalysts, CO poisoning, high free energy barriers during oxidation processes pose significant obstacles to catalysts' ability cleave C─C bonds for complete oxidation. Here, series PdCuCo metalene electrocatalysts is reported, wherein varying intermetallic interactions among Pd, Cu, Co...

In order to maximize the Pt utilization in catalysts and improve catalytic processes, we report a convenient strategy for preparation of Pt3Co with Pt-skin structured bimetallic nanocatalysts directly supported on porous graphitic carbon. Notably, thickness is only 1–2 atomic layers, about 0.5 nm.
