Grafting photocatalytic metal oxides (ZnO, TiO2) on mesoporous silica via metalorganic route
Résumé
Our objective was to explore chemical strategies based on organometallic precursors in organic solvents to yield unprecedented TiO2- or ZnO-decorated SBA-15. We synthesized hybrid materials (TiO2/SBA-15 or ZnO/SBA-15) from various organometallic precursors such as tetrakis(ethylmethylamido) titanium (TEMAT), titanium tris-amidinate (Ti-Amd) and dicyclohexyl zinc (Zn(Cy)2), and under various hydration conditions. In future work, the efficiency of such materials will be assessed under injection of 400 ppb NO.
