Grafting photocatalytic metal oxides (ZnO, TiO2) on mesoporous silica via metalorganic route for air depollution
Résumé
We synthesized hybrid materials TiO2/SBA-15 from the organometallic precursors TEMAT (tetrakis(ethylmethylamido) titanium) and Ti-Amd (titanium tris-amidinate). In this work, we focused on the TiO2/SBA-15 material obtained from TEMAT. We characterized this hybrid material and assessed its air depollution properties at the scale of a laboratory reactor (glass substrate, injection of 400 ppb of NO under UV-A light). Results showed that TiO2 was successfully incorporated into SBA-15. NO degradation was observed with the synthesized hybrid material.
