Metallosilicate catalysts with tetrahedrally coordinated transition metals covalently incorporated into the silica framework are attractive for their highly selective oxidation activity towards a wide variety of hydrocarbons. This study demonstrates that titanium acetylacetonate (Ti(acac)4), as a metal complex, is an excellent candidate for the preparation of metallosilicate catalysts.
In this work, the researchers grafted titanium (IV) acetylacetonate onto the surface of various porous silica supports to prepare Ti-containing porous silica. The specific preparation steps include ultrasonication, stirring reaction, solvent removal, centrifugal separation, drying and calcination of porous silicon dioxide and Ti(acac)4.
The results showed that with the increase of Ti content, Ti-grafted MCM-41 exhibited higher catalytic activity for epoxidation. Furthermore, the Ti-grafted catalyst exhibited high catalytic performance in the epoxidation of plant-derived olefin limonene.
