Abstract

We present a synthesis route for solid-state nanocatalysts composed of gallium phosphide nanowire supports decorated with catalytic palladium nanoparticles. Through precise control of fabrication conditions, we were able to tune the nanowire morphology, density, and crystal structure. The resulting catalysts were highly active and selective in the partial hydrogenation of phenylacetylene to styrene. Size-selected palladium nanoparticles deposited in the aerosol form primarily settle on the upper sidewalls of tapered nanowires, retaining crystallinity and shape. Adjustable nanocatalyst fabrication conditions allow tuning of surface wettability. Hydrophobic, low-density nanocatalysts show enhanced activity in hydrogenation reactions.... (More)

The resulting catalysts were highly active and selective in the partial hydrogenation of phenylacetylene to styrene. Size-selected palladium nanoparticles deposited in the aerosol form primarily settle on the upper sidewalls of tapered nanowires, retaining crystallinity and shape. Adjustable nanocatalyst fabrication conditions allow tuning of surface wettability. Hydrophobic, low-density nanocatalysts show enhanced activity in hydrogenation reactions. Exploring these fabrication parameters enables a tailored design of heterogeneous nanocatalysts and provides insights into the critical factors influencing their functionality.
