Facet engineering accelerates spillover hydrogenation on highly diluted metal nanocatalysts

by Lizhi Jiang

Nature Nanotechnology, Published online: 03 August 2020; doi:10.1038/s41565-020-0746-x

Spillover hydrogenation is facet specific and occurs on atomically dispersed Pd catalyst on Cu(100). Knowing this, cost-effective catalysts with extremely low Pd loading are fabricated that successfully catalyse the semi-hydrogenation of a broad range of alkynes with high activity and selectivity.
