Hydrogen Spillover Boosted Hydrogen Evolution Electrocatalysis over Pd@CoP in Alkaline Seawater

ACS Materials Letters, Journal Year: 2024, Volume and Issue: 6(9), P. 3970 - 3976

Published: July 29, 2024

Developing efficient and stable electrocatalysts for the hydrogen evolution reaction (HER) is crucial to achieve effective electrolytic production from seawater. Hydrogen spillover enhances catalytic performance by facilitating migration of species between different sites, improving efficiency kinetics in HER. Herein, we report hydrothermal-phosphatization-immersion synthesis Pd-decorated CoP nanoneedle arrays on nickel foam (Pd@CoP/NF) as a highly active HER electrocatalyst toward alkaline seawater reduction. In situ electrochemical impedance spectroscopy kinetic isotope effects reveal Pd@CoP/NF's extensive adsorption enhanced transfer rates. seawater, such Pd@CoP/NF exhibits outstanding with low overpotential 249 mV at current density 1000 mA cm–2 long-term stability 500 h.

Interface Coordination Engineering of P-Fe3O4/Fe@C Derived from an Iron-Based Metal Organic Framework for pH-Universal Water Splitting

Nanomaterials, Journal Year: 2023, Volume and Issue: 13(13), P. 1909 - 1909

Published: June 22, 2023

Developing electrocatalysts with high energy conversion efficiency is urgently needed. In this work, P-Fe3O4/Fe@C electrodes rich under-coordinated Fe atom interfaces are constructed for efficient pH-universal water splitting. The introduction of atoms into the interface can increase local charge density and polarize 3d orbital lone electrons, which promotes adsorption activation to release more H*, thus elevating electrocatalytic activity. As a donor-like catalyst, displays excellent performance overpotentials 160 mV 214 in acidic alkaline electrolytes at 10 mA cm−2, addition long-term stability.
