Microwave quasi-solid-constructed Ni₂P-Ni₁₂P₅-supported Os with unique metal-support interaction for anion-exchange membrane seawater electrolysis.

ABSTRACT: Highly efficient and corrosion-resistant electrocatalysts for the seawater hydrogen evolution reaction (HER) are crucial for large-scale hydrogen production. Herein, Ni₂P-Ni₁₂P₅-supported Os (Os/Ni₂P-Ni₁₂P₅) was synthesized within 30 s via an ultrafast and simple microwave quasi-solid approach. This fabricated interface improves the electron transfer efficiency, while metal-support interaction (MSI) between Os and Ni₂P-Ni₁₂P₅ further optimizes the electronic structure, and then significantly expedites the HER process. The electrocatalyst presents excellent performance in alkaline seawater with a low overpotential of 17 mV to reach the current density of 10 mA cm^-2. In simula
