Preparation of highly loaded platinum nanoparticles on silica by intercalation of [Pt(NH3)4]2+ ions into layered sodium silicate ilerite

Highly loaded Pt nanoparticles (20 wt%) on silica were prepared by intercalation of [Pt(NH^sub 3^)^sub 4^]^sup 2+^ ions into layered sodium silicate ilerite at room temperature, followed by calcination of the intercalated ilerite ([Pt(NH^sub 3^)^sub 4^]^sup 2+^ ilerite) in air at 380 °C for 5 h. Tra...

Zusammenfassung:	Highly loaded Pt nanoparticles (20 wt%) on silica were prepared by intercalation of [Pt(NH^sub 3^)^sub 4^]^sup 2+^ ions into layered sodium silicate ilerite at room temperature, followed by calcination of the intercalated ilerite ([Pt(NH^sub 3^)^sub 4^]^sup 2+^ ilerite) in air at 380 °C for 5 h. Transmission electron microscopy revealed that the size of the Pt particles was in the range 2-5 nm.[PUBLICATION ABSTRACT]
