Because the alumina nanorods stabilized Pt nanoparticles, the sintering of Pt nanoparticles was significantly suppressed during a high temperature water gas shift reaction, demonstrating 1.7-13.6 times higher CO conversions or 1.0-8.0 times higher TOF compared to other alumina-supported Pt catalysts. In addition, the increased metal-support interface for Pt@Al2O3 significantly improved the water gas shift reaction activity. (C) 2014 Elsevier B.V. All rights reserved.
