CATALYSTS WHICH ARE BASED ON ORGANIC-INORGANIC HYBRID MATERIALS CONTAINING NOBLE METALS AND TITANIUM AND WHICH ARE USED FOR SELECTIVELY OXIDIZING HYDROCARBONS

摘要

The invention relates to compositions containing gold and/or silver particles and organic-inorganic hybrid materials that contain titanium, whereby these hybrid materials contain Si-H groups. The invention also relates to a method for producing these compositions and to their use as catalysts for selectively oxidizing hydrocarbons. The catalytically active compositions exhibit high selectivities and productivities as well as very long catalyst lifetimes without deactivation.
