CeO₂ nanorods and nanocubes, which were used as supports to Pd (3.0 wt.%)/CeO₂ catalysts, which were prepared by hydrothermal method. TEM, HRTEM, XRD, and H₂-TPD were used to study the physic-chemical properties of the Pd/CeO₂ catalysts. The Pd/CeO₂ 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/CeO₂ catalysts exhibit morphology-dependent catalytic activity. The Pd/CeO₂ 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.

CeO ₂纳米棒和纳米立方体用作水热法制备的Pd（3.0 wt％）/ CeO ₂催化剂的载体。TEM，HRTEM，XRD和H ₂ -TPD用于研究Pd / CeO ₂催化剂的物理化学性质。利用Pd / CeO ₂催化剂研究了在大气压下于100–200°C的温度下气相苯催化的加氢反应。结果表明，Pd / CeO ₂催化剂表现出形态依赖性的催化活性。Pd / CeO ₂纳米棒催化剂（PC100）具有优异的气相苯催化加氢性能。苯催化加氢转化率和在200°C下的环己烷选择性分别为96.4％和100％。
