CeO 2 nanorods and nanocubes, which were used as supports to Pd (3.0 wt.%)/CeO 2 catalysts, which were prepared by hydrothermal method. TEM, HRTEM, XRD, and H 2 -TPD were used to study the physic-chemical properties of the Pd/CeO 2 catalysts. The Pd/CeO 2 catalysts were applied to investigate the vapor phase benzene catalytic hydrogenation reaction under atmospheric pressure at the temperature of 100–200 °C. Results show that the Pd/CeO 2 catalysts exhibit morphology-dependent catalytic activity. The Pd/CeO 2 nanorod catalyst (PC100) has a superior vapor phase benzene catalytic hydrogenation performance. The benzene catalytic hydrogenation conversion and cyclohexane selectivity are 96.4% and 100% at 200 °C, respectively. [ABSTRACT FROM AUTHOR]
