Selective and Long-Term Stable Ammonia Electrolysis Using Pt-WO_x Catalysts with Suppressed NO_x Formation and Enhanced Activity.

ABSTRACT: Ammonia electrolysis presents a promising strategy for low-voltage hydrogen production; however, its advancement is impeded by limitations in electrocatalyst performance due to sluggish reaction kinetics and deactivation caused by strongly adsorbed nitrogen-containing intermediates. In this study, a photodeposited Pt on tungsten suboxide (WO_x) nanowires (Pt-WO_x (P)) is introduced as a bifunctional electrocatalyst for ammonia electrolysis. The photodeposition induces strong metal-support interaction, resulting in robust interfacial bonding between Pt and WO_x and facilitating electron transfer from WO_x to Pt.
