Abstract
An as-synthesized zeolite having titanium substituted in its lattice framework and containing an organic template such as a quaternary ammonium salt may be activated for use as a catalyst by treating said as-synthesized zeolite with ozone. At least partial removal and/or reaction of the organic template is accomplished even at moderate temperatures, in contrast to conventional calcination techniques which require the use of significantly higher activation temperatures.
