SiliaCat®- Heterogeneous Catalysts Product Range

SiliCycle, a leader in functionalized silica gels, has developed various catalysts at competitive prices.

SiliaCat Dpp-Pd (R390-100)
Structure Structure-SiliaCat-DPP-Pd
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.
Typical Applications Suzuki, Heck, Sonogashira,, Kumada, Stille

SiliaCat Pd0 (R815-100)
Structure Structure-SiliaCat-Pd0
Brief Description SiliaCat Pd0 is a new series of patent-protected sol–gel-entrapped Pd nanocatalysts. It is made from highly dispersed Pd nanoparticles (uniformly in the range 4.0–6.0 nm) encapsulated within an organosilica matrix.
Typical Applications Suzuki, Heck Sonogashira, Kumada, Stille, Selective debenzylation, Selective hydrogenation
SiliaCat Typical Characteristics Color Dark brown to black
Endcapping Yes
Molecular Loading -
Typical Tap Density -
Solvent Compatibility All solvents, aqueous and organic
Prolonged Storage Keep cool (< 8 °C) Under Argon

SiliaCat Pt0 (R820-100)
Structure Structure-SiliaCat-Pt0
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
SiliaCat Typical Characteristics Color Dark brown to black
Endcapping Yes
Molecular Loading -
Typical Tap Density -
Solvent Compatibility All solvents, aqueous and organic
Prolonged Storage Keep dry Under Argon

SiliaCat TEMPO (R723-100)
Structure Structure-SiliaCat-TEMPO
Brief Description SiliaCat TEMPO is a new oxidizing catalyst made from a proprietary class of organosilica-entrapped radicals. This encapsulation process confers enhanced reactivity and properties. The leach-resistant organoceramic matrix makes SiliaCat TEMPO highly efficient and selective compared to homogeneous TEMPO reagents. It also has a superior performance compared to polymer-supported TEMPO and silica-supported TEMPO in terms of both selectivity and stability. With SiliaCat TEMPO, no activation is required prior to use and selective aldehyde vs acid oxidation is possible.
U.S.Patent: 6,797,773 B1,2004
Typical Applications Oxidation of alcohols or Aldehydes
SiliaCat Typical Characteristics Color Orange
Endcapping Yes
Molecular Loading ≥ 0.70 mmol/g
Typical Tap Density 639 g/L
Solvent Compatibility All solvents, aqueous and organic
Prolonged Storage Keep dry
