Controlling the precise growth of atoms is necessary to achieve manipulation atomic composition and position, regulation electronic structure, an understanding reactions at level. Herein, we report a facile method for ordered anchoring zero-valent platinum manganese with single-atom thickness on graphdiyne under mild conditions. Due strong incomplete charge transfer between metal atoms, formation clusters nanoparticles can be inhibited. The size, structure bimetallic nanoplates are precisely controlled by natural structure-limiting effect graphdiyne. Experimental characterization clearly demonstrates such fine control process. Electrochemical measurements show that active site platinum-manganese interface guarantees high catalytic activity selectivity (~100%) alkene-to-diol conversion. This work lays solid foundation obtaining high-performance nanomaterials engineering site. reports growing highly Pt Mn single layers fully activates loaded results in electrocatalytic conversion

Abstract Orbital hybridization is a promising approach to modulating the electronic structure of designed electrocatalysts boost reaction kinetics. In contrast d‐d hybridization, p‐d orbital between p‐block elements and d‐block metals can provide new opportunities modulate properties thus promote catalytic performance. Herein, phosphorus‐doped osmium (P‐Os) catalyst through ultrafast (20 s) microwave plasma engineering. Theoretical calculations verify d‐p P Os, leading modulation d‐band center Os active site. Specifically, neighboring exhibit highest activity, facilitating crucial processes such as H 2 O/H* adsorption dissociation. The overpotential P‐Os in alkaline seawater only 152 mV at 1 A cm −2 , which superior reported electrocatalysts. Moreover, synthesized catalysts are integrated into an anion exchange membrane (AEM) electrolyzer, demonstrating remarkable AEM electrolyzer requires 1.86/2.02 V achieve 500/1000 mA current densities. Then, achieved have great potential for practical electrocatalytic water‐splitting applications.

The H2O-participating electrochemical hydrogenation (ECH) of benzonitrile represents a mild and efficient method for benzylamine synthesis, but the kinetics Faraday efficiency are still limited. Herein, developed Pd clusters dispersed Cu nanoparticles encapsulated in porous carbon (Pdn-Cu@C) achieves ECH (C6H5CN) to benzylamines (C6H5CH2NH2). In situ infrared spectroscopy theoretical studies reveal that Pd/Cu interface functions as active site hydrogen (*H) generated by H2O dissociation, enhances adsorption C6H5CN, weakens C6H5CH2NH2. Moreover, Gibbs free energy barriers *H spillover much lower than self-coupling. As expected, Pdn-Cu@C exhibits electro-hydrogenation C6H5CN with conversion 97.42%, high C6H5CH2NH2 selectivity 97.21%, Faradaic 92.10% under specific voltage. This finding blazes feasible trail suppress competitive self-coupling offers insights multistep protonation reactions.
