A new process for the synthesis and stabilization of gold nanoparticles within the cavities of propylamine functionalized mesoporous MCM-41 material is described wherein silanol groups present on the inner surface of the mesoporous silica reduce aqueous chloroaurate ions to form the Au nanoparticles, and the amine groups anchor the nanoparticles thus formed in the inner surface of the cavities. The nano-Au-NH2-MCM-41 hybrid material was characterized by XRD, UV-Vis spectroscopy, EDX, TG-DTA and N2 adsorption measurements. Further, this nano-Au-NH2-MCM-41 material shows promising catalytic activity and selectivity in the hydrogenation of styrene to ethylbenzene.
