Engineering an atomically well defined active site for the catalytic epoxidation of alkenes

Abstract

The improvement effected by replacing one of the three O–Si[triple bond, length half m-dash] groups to which a Ti^IV ion is anchored (to a mesoporous silica support) by a O–Ge[triple bond, length half m-dash] group is described, as is the detailed structure retrieved by in situ X-ray absorption spectroscopy of the created active site.
