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.
