Abstract
The present disclosure generally relates to a silver-based epoxidation catalyst. In certain embodiments, a method is provided for modulating the reactivity of the silver-based epoxidation catalyst, comprising the catalyst being post-treated with at least two different salt solutions. In some embodiments, the treatment results in the deposition of one or more metals onto the surface of the catalyst. In further embodiments, method is also provided of using the silver catalyst to generate an epoxide from an olefin.
