SiliaCat is the new heterogeneous catalysts family from Silicycle. It is made by using an innovative technology that confers these materials advantageous properties for catalysis. SiliaCat is an organically modified silica made by a proprietary encapsulation process resulting in a new chemical matrix structure.1
SiliaCat is a leach-proof organoceramic matrix with high catalyst loading and surface area that provides high turn over number (TON).

Like any other silica-based material, SiliaCat presents the following:
The organosilica-based matrix of the SiliaCat offers the following catalyst advantages:

The significant costs associated with precious metal catalysts and their undesired tendency to remain in organic products has generated interest for an increase in reactivity and ways to recover and reuse these metals. SiliaCat® DPP-Pd is a unique diphenylphosphine palladium (II) heterogeneous catalysts made from a leach-resistant organoceramic matrix.
The significant costs associated with precious metal catalysts and their undesired tendency to remain in organic products has generated interest for an increase in reactivity and ways to recover and reuse these metals. SiliaCat® S-Pd is a unique thiol based palladium (II) heterogeneous catalysts made from a leach-resistant organoceramic matrix.
SiliaCat® TEMPO is a heterogeneous catalyst/reagent made from a proprietary class of organosilica-entrapped radicals suitable for the selective oxidation of delicate substrates into valued carbonyl derivatives.
