Isomorphic Substitution and Postsynthesis Incorporation of Zirconium into MCM-48 Mesoporous Silica

We describe the introduction of zirconium metal centers into the cubic phase of mesoporous silica. Two methods of zirconium incorporation were compared consisting of hydrothermal Si/Zr coprecipitation and postsynthesis functionalization of surface silanols with zirconium propoxide. Nitrogen sorption...
