Highly dispersed and tiny-sized noble metal nanoparticles are deposited on a hairy poly(4-vinylpyridine)-silica support, which can serve as recyclable heterogeneous catalysts in the reductive degradation of 4-NP and RhB dye pollutants.

Mesoporous Organosilicas

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.

Voc Abatement

The continuous production of Pt-based heterogeneous catalysts based on ultra-small (<2 nm) noble metal nanoparticles deposited on mesoporous ordered silica and their catalytic activity in VOC abatement are here reported. Commercially available micromixers can be easily interfaced to create a multistage platform which allows the growth of metal noble NPs as well as their alloys.
