Mapping current high-entropy materials for water electrolysis: from noble metal to transition metal

“…In multiple metal materials, especially for HEMs, the metallic electronic interaction may increase the oxidation state of one key element, enhance the covalency of the M–O bond, activate lattice oxygen and even widen the d-band for efficient adsorption modulation. 64–67 The HEMs may be excellent candidates for catalyzing OER by microscopic mechanism optimization.…”

Phosphorus-Doped PdSn Nanowires for Electrocatalytic Alcohol Oxidation

“…Recent studies have shown that one of the key factors affecting the catalytic efficiency of palladium-based nanocatalysts is the catalytic active site on the catalyst surface, and the catalytic efficiency of palladium-based catalysts can be greatly improved by constructing abundant catalytic active sites . The introduction of defects in palladium-based nanocatalysts is the most direct way to construct catalytic active sites. − And among the different types of defects introduced, interfacial defects in the construction of heterogeneous structures show unique advantages. − The palladium atoms at interfacial defects have more uncoordinated bonds and high surface energy, which can effectively strengthen the interaction between palladium atoms and alcohol molecules so that alcohol molecules are more easily adsorbed on the surface of palladium atoms, thus improving the catalytic efficiency. , However, at present, the conditions for constructing such multiphase interfacial palladium-based catalysts are harsh, and the steps are complicated. Furthermore, the synthesized multiphase structures have poor controllability.…”

Modulating the localized electronic distribution of Cu species during reconstruction for enhanced electrochemical CO2 reduction to C2+ products

“…With the improvement of industrialization and the acceleration of urbanization, the concentration of carbon dioxide (CO 2 ) in the earth's atmosphere is increasing rapidly, causing the deterioration of the environment and ecology. 1–10 The conversion of CO 2 into valuable chemical fuels through electrochemistry can benefit from being powered by green electricity and is easy to modularize and scale up, and is regarded as one of the most promising technologies for carbon neutrality. 11–14 Catalysts as the core of the CO 2 RR have been extensively studied, and multiple catalysts have been designed to achieve different products, such as CO, 15 formate, 16 ethanol, 17 and ethylene.…”
