Abstract

Uniformly dispersed Pt nanoparticles with controlled size and loading supported on multi-walled carbon nanotubes (CNTs) are synthesized by atomic layer deposition (ALD) with (methylcyclopentadienyl)trimethylplatinum (MeCpPtMe₃) as the Pt precursor and ozone as the reactant gas. All the ALD-prepared Pt/CNT catalysts with various cycle numbers show excellent catalytic activities towards hydrolysis reaction of ammonia borane (AB), and especially the Pt/CNT catalyst produced with 20 ALD cycles exhibits the highest hydrogen generation rate among the ALD-prepared catalysts, with a total turnover frequency value as high as 416.5 mol_H2 mol_Pt ^-1 min^-1. The porous TiO₂ overcoat further improves the durability of the Pt/CNT catalysts while preserving their catalytic activities.
