Preparation of Ruthenium Hollow Spheres as Catalysts for Selective Hydrogenation of Benzene to Cyclohexene

Abstract:

In this paper, a simple and effective method was used to synthesize monodisperse metal Ruthenium nanospheres (Ru-HNSs), and the silicon dioxide (SiO₂) nanospheres synthesized by Stober method were used as hard templates. The surface of SiO₂ was double modified by γ-aminopropyltriethoxysilane (KH550) and salicylaldehyde, so that Ru³⁺ grew uniformly on the surface of modified SiO₂ and reduced to form a stable and durable layer of Ru metal. Then the hard template SiO₂ was corroded by chemical etching to obtain Ru-HNSs hollow spheres. The results show that the diameter of SiO₂ microspheres was about 300nm, the wall thickness of Ru-HNSs was about 3nm, and the diameter was about 100nm.
