“…Most of the approaches reported to date follow the classical gelation mechanism and are summarized elsewhere. [3][4][5][127][128][129] Thew ork by Gash and colleagues, wherein they introduced propylene oxide as an efficient reactant to obtain metal oxide gels without the need for the commonly used toxic and expensive alkoxide precursors generated ag reat deal of interest. [130] This alternative approach resolved the problems of the commercial availability and the difficult hydrolysis kinetics of the alkoxide precursors especially for the preparation of mixed transition metal oxide aerogels.T he method was extended to several metal oxide systems such as Al 2 O 3 ,C eO 2 ,Z nO,S nO 2 ,T iO 2 , SiO 2 ,NiO 2 ,Fe 2 O 3 ,and others.…”

“…Mixed oxide aerogels are of special interest due to their high surface acidity, large surface area and thermal stability [127]. SiO 2 /TiO 2 hybrid aerogel is used as a photoanode material in DSSC and exhibits a power conversion efficiency of 9.41%.…”

“…Metalloxide gehçren zu den am häufigsten studierten Materialien in der Aerogelforschung.D ie meisten bisher berichteten Ansätze folgen dem klassischen Gelbildungsmechnismus und sind an anderer Stelle zusammengefasst. [3][4][5][127][128][129] Besondere Aufmerksamkeit weckte die Arbeit von Gash et al,i nd er sie Propylenoxid als einen effektiven Reaktanten zur Herstellung von Metalloxidgelen einführten, was den Bedarf der üblicherweise genutzten giftigen und teuren Alkoxidvorstufen überflüssig machte. [130] Dieser alternative Ansatz lçste sowohl das Problem der schlechten kommerziellen Verfügbarkeit als auch dasjenige der schwierigen Hydrolysekinetik der Alkoxidvorstufen bei der Synthese von gemischten Übergangsmetalloxidaerogelen.…”
