Selective hydrogenation of o-chloronitrobenzene using supported platinum nanoparticles without solvent
2012
Abstract Colloidal platinum nanoparticles with 2.2 nm were immobilized on γ-iron oxide (γ-Fe 2 O 3 ) powder to make a supported catalyst (Pt/γ-Fe 2 O 3 ) with controlled Pt nanoparticle size and size distribution. This catalyst was used to catalyze the selective hydrogenation of o -chlorobenzene to o -chloroaniline without using any solvent; 99.9% selectivity at 99.95% conversion was achieved.
