platinum nanoparticles (Pt NPs) hybrided with nanostructured carbon
materials with high stability are important for catalyzing hydrogenation
reaction. Here we reported the fabrication of ultrastable Pt NPs anchored
on graphdiyne, in which the strong interactions induced by the porous
graphdiyne can prevent the thermal migration of Pt nanoparticles on
the graphdiyne surface, exploiting the strong charge transfer interactions
from Pt NPs to GDY substrate to tune the electron density of Pt NPs.
Pt NPs catalyst with size of 2–3 nm showed high performance
on hydrogenation of aldehydes and ketones to the corresponding alcohols
compared with commercial Pt–C. Our results indicated that graphdiyne
is a promising substrate for constructing metal nanoparticle-based
heterogeneous catalysts, especially for those requiring strong interactions
between metal nanoparticles and reactants.
