The Isocyanurate-Carbamate-Bridged Hybrid Mesoporous Organosilica: An Exceptional Anchor for Pd Nanoparticles and a Unique Catalyst for Nitroaromatics Reduction

نویسندگان

چکیده

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