Rhodium(0) nanoparticles supported on ceria (Rh NPs/CeO) were prepared from the reduction of Rh ions on the surface of ceria in aqueous medium. Rh NPs/CeO catalyst was found to be highly active in hydrogenation of benzene under mild conditions. It provided a TOF value of 495 h in hydrogenation of solventless benzene under ∼3 bar pressure of H gas at 25.0 ± 0.1 °C. Rh NPs/CeO shows superior catalytic activity over titania, zirconia and hafnia supported Rh NPs in this reaction.
铑（0）纳米粒子负载在氧化铈上（Rh NPs/CeO）是通过在水相介质中还原氧化铈表面的铑离子制得的。Rh NPs/CeO 催化剂在温和条件下的苯加氢反应中表现出很高的活性。在 25.0±0.1°C、约 3 巴氢气压力下，无溶剂苯加氢反应中，其提供的 TOF 值为 495 h。在该反应中，Rh NPs/CeO 相对于负载在二氧化钛、氧化锆和氧化铪上的 Rh NPs 具有更高的催化活性。
