Local Atom Disorder Mediated Crystal Facet Valence State of PtCu Alloy for Ultrafast Ammonia Oxidation Dehydrogenation
Listed in ScienceDB
Pt (200) facet of platinum-based alloys exhibit high potential in ammonia oxidation reaction (AOR), but is still a huge bottleneck in activity enhancement due to the sluggish NHx-dehydrogenation kinetics and H-poisoning.
Description
Herein, a novelly local-disordered PtCu alloy, with an increasing low-valence-platinum ratio on the (200) facet by H2/Ar post-annealing ambient, was engineered to atomically boost AOR dehydrogenation behaviour through the reconstruction microenvironment of Pt (200) plane.
