Nanometer scale restructuring of alumina carrier surface and catalysts for the production of alkene oxides

摘要

A carrier and a catalyst useful for the oxidation of ethylene to ethylene oxide which uses the carrier. The carrier is composed of an inert, refractory solid support such as alpha alumina and has a surface exhibiting a plurality of nanometer scale protrusions projecting outwardly from the surface, and has a catalytically effective amount of silver thereon.
