SiliaCat Dpp-Pd | R390-100

Structure

Brief Description

The significant costs associated with precious metal catalysts and their tendency to remain in organic products has generated interest for solutions that increase reactivity and can enable the recovery and reuse of these metals. SiliaCat DPP-Pd is a unique diphenylphosphine palladium (II) heterogeneous catalyst made from a leach-resistant organoceramic matrix.

SiliaCat Pt⁰ | R820-100

Structure

Brief Description

SiliaCat Pt⁰ is made of organosilica physically doped with nanostructured platinum (0), and is both stable and efficient. This catalyst was successfully prepared by a novel and simple sol-gel route. In the new procedure, Pt nanoparticles (uniformly in the range 1.7–3.15 nm) are encapsulated via an alcohol-free sol-gel process typical of enzyme sol-gel encapsulation.

Typical Applications

Selective reduction of nitroarenes, Hydrosilylation
