Abstract
Mesoporous materials are very attractive materials because of their high surface area and therefore used for various applications such as catalyst supports, absorbents, photocatalysts, electrode materials, etc. So far applications of mesoporous materials have mainly been restricted to silica, alumina, titania and carbon, but recently a range of new mesoporous metal oxides have been synthesized. They often possess very interesting properties that differ completely from their bulk counterparts. Although many interesting applications utilizing mesoporous metal oxides may emerge, the synthesis is mostly limited to monometalic oxides. In this research we developed and optimized a synthesis route that can be applied to synthesize various multimetalic oxides. With the aim to synthesize mesoporous SrTiO3 for energy conversion applications, several precursor solutions were synthesized and impregnated into a mesoporous silica template. The influence of the chelating agents, pH and solvent nature on the impregnation efficiency and the quality of the final mesoporous ceramics were investigated. An optimized synthesis route was based on the impregnation of a SrTiO3 percursor solution containing iminodiacetic acid, H2O2 and ethanolamine in a H2O - EtOH mixture. A Sr/Ti ratio of about 1 could be obtained which yielded crystalline mesoporous SrTiO3 after calcination and template removal.
