Abstract

Intermetallic CaPt₂ nanoparticles, supported on titanium group oxides, were prepared using a molten salt method with CaH₂ as both the reducing agent and the calcium source. The nanoparticles exhibited superior catalytic activity compared to a commercial Pt/C catalyst in the hydrogenation of ketones to alcohols, which could be promoted by electron-rich Pt sites in CaPt₂.
