Abstract
Pt nanoparticles stabilized with alumina nanorods (Pt@Al2O3) were synthesized by a simple preparation method using a mixture of Pt nanoparticles, an alumina precursor, an organic surfactant, and a reducing agent. 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.
