NOVEL METAL SILICATE COMPOSITIONS AND CATALYSTS

摘要

A high silica zeolite (UTD-1) using bis(pentamethyl-cyclopentadienyl)cobalt(III) hydroxide, Cp*2CoOH is disclosed. UTD-1 is a large pore molecular sieve having one-dimensional channels running in parallel. The synthesis and characterization of silicates incorporating titanium, vanadium, aluminum or boron in the silicate framework is described. Calcined Ti-UTD-1 containing cobalt oxide and the cobalt free molecular sieves are shown to be effective oxidation catalysts. Oxidation of alkanes with hydrogen peroxide and t-butylhydroperoxide (t-BHP) and the room temperature oxidation of cyclohexane to adipic acid are demonstrated.
