The electrochemical methanol–hydrogen transformation as a significant technique for hydrogen generation is limited by low Pt catalytic efficiency. Herein, the doping and interfacial support engineering of MoSe2 nanosheets NH3 plasma confined in mesoporous hollow-carbon-spheres-supported nanoparticles (Pt/N-MoSe2@MHCS) were demonstrated novel platform catalyzing methanol electrolysis. Experiments density functional theory (DFT) calculations confirm that band structure species downshifted to weaken adsorption energy COad/Had, resulting improved CO-poisoning resistance accelerated electrocatalytic kinetics. As result, Pt/N-MoSe2@MHCS shows highest current 99.2 mA cm–2 oxidation overpotential 26 mV@10 evolution. methanol-assisted water electrolyzer assembled showed cell voltage 1070 mV reach 10 cm–2. This work provides guidance design reasonable noble-metal catalysts electrolysis production.

Replacing platinum-group metals by Ni-based catalysts for the alkaline hydrogen oxidation reaction (HOR) is highly desired anion-exchange membrane fuel cells (AEMFCs), while huge challenges still exist due to sluggish kinetics and oxidative deactivation of Ni active centers. Herein, we report an ingenious design microstructured electrocatalysts featured nanoparticulate NiMo alloy cores encapsulated N-doped carbon layer shells (NiMo-5%@NC) address these problems. Electrochemical experiments theoretical calculations confirm that confinement effect can rationally weaken binding energy oxygenated species through direct interactions with layers rather than relying on traditionally regulated electronic structures surfaces. This ultimately reduces barrier water formation, potential-determining step HOR undergoing bifunctional path. Moreover, incorporation not only enhances passivation resistance surfaces but also alleviates dissolution alloyed Mo-species, resulting in obviously improved stability. As a result, NiMo-5%@NC exhibits significantly activity stability compared counterpart without protection (NiMo-5%). work shows comprehensive insights into exerted shells, providing different light guidelines deal centers AEMFCs.

The development of highly efficient and durable alkaline hydrogen evolution reaction (HER) catalysts is crucial for achieving high-performance practical anion exchange membrane water electrolyzer (AEMWE) at ampere-level current density. Herein, we report a design concept by employing Ga single atoms as an electronic bridge to stabilize the Ru clusters boosting HER performance in AEMWE. Experimental theoretical results collectively reveal that bridged sites trigger strong metal-support interaction homogeneous distribution with high density, well optimize Ru-H bond strength due electron transfer between enhanced intrinsic activity.
