Photothermal-promoted anion exchange membrane seawater electrolysis on a nickel-molybdenum-based catalyst.

ABSTRACT: Exploring active, durable catalysts and utilizing external renewable energy sources offer notable opportunities for advancing seawater electrolysis. Here, a multifunctional NiMo-based catalyst (NiMo-H₂) composed of bimetallic Ni_0.91Mo_0.09 nanoparticles on MoO₂ nanorods is demonstrated for the alkaline seawater hydrogen evolution reaction. The alloying effect and the nanorod-nanoparticle structure endow this catalyst with high structural stability, rapid electron transfer, and a large surface area. The in situ-generated alloyed nanoparticles have notable light absorption and photothermal conversion capabilities, while the vertically grown nanorods suppress diffuse reflection, enabling efficient localized photoheating. Consequently, light irradiati
