In this work, a ternary composite, Pt/TiO2/RGO (reduced graphite oxide), was prepared via immobilizing Pt particles onto the TiO2/RGO composite that was obtained via redox reaction of TiCl3 and GO. The composite was characterized by different techniques including X-ray diffraction, transmission electron microscopy, and X-ray photoelectron spectroscopy. The TiO2 particles with size less than 10 nm were uniformly distributed throughout the RGO, and almost each Pt particle with size around 3 nm adhered to TiO2 particles, resulting in high dispersion of all Pt particles on the support. The Pt particles were in the electron-deficient state due to the strong interactions with the TiO2 particles and the RGO support. The catalytic performance of the composite for nitrobenzene hydrogenation was investigated under solvent-free condition. It was indicated that the Pt/TiO2/RGO catalyst exhibited high activity with a turnover frequency (e.g., 59,000 h(-1)) as well as superior selectivity to aniline (e.g., >99%). Moreover, the catalyst can be reused for six times without any activity loss, which resulted from the stable structure of the catalyst. (C) 2012 Elsevier Inc. All rights reserved.
