Heterogeneous catalysts are considered one of the key technologies as the chemical industry seeks to become more sustainable. The ‘Green Chemistry’ allowed by the use of such materials offers significant environmental as well as operational benefits to chemical processes, which are pivotal to the pharmaceutical, biotechnology, fine chemical and petrochemical sectors.

PhosphonicS™ has designed and developed a portfolio of heterogeneous catalysts, based on functionalised silicas, for metal-mediated oxidations, acid-promoted reactions and metal-mediated cross coupling reactions. These highly effective and selective catalysts can be easily filtered off, washed and recycled.

A developing range of Immobilised Enzymes are also in development

Immobilised ligands such as phosphines are also available
