Hybridisation of mesoporous organosilicas (MO) to reinforce the surface capability in adsorption and stabilisation of noble metal nanoparticles is of great attention in generating/supporting noble metal within their matrices and transforming them into efficient heterogeneous catalysts. Here, we used a unique hybrid of organic-inorganic mesoporous silica in which pore profile pattern was similar to the well-known mesoporous silica, SBA-15 for catalysis. This hybrid mesoporous organosilica was further engaged as a support in the synthesis and stabilisation of Pd nanoparticles on its surface, and then, the obtained Pd-supported MO was employed as a heterogeneous green catalyst in the conversion of aqueous p-nitrophenol (PNP) to p-aminophenol (PAP) at room temperature with efficient recyclability.

Abstract Hybridization of mesoporous organosilica (MO) to reinforce the surface capability in adsorption and stabilization of noble metal nanoparticles are of great attention in generating noble metal-based catalysts. Here, we used a unique hybrid of organic-inorganic mesoporous silica which in pore profile pattern was similar to the well-known mesoporous silica, SBA-15. This hybrid mesoporous silica was further incorporated in the synthesis and stabilization of Pd nanoparticles on its surface and then, the obtained Pd supported MO, was employed as a heterogeneous green catalyst in the conversion of p-nitrophenol (PNP) to p-aminophenol (PAP) at room temperature with efficient recyclability.
