Influence of drying technique on Pt/In2O3 aerogels for methanol steam reforming

Abstract In this paper we present a comparison of aerogels which are dried under different conditions. Of those, most important the solvent, temperature, and pressure. Criteria rely mostly on results from analysis nitrogen adsorption experiments, as well transmission electron microscopy imaging. Platinum loaded indium oxide were picked model system for study they can be used highly effective heterogeneous catalysts in methanol steam reforming. The compared drying methods include supercritical CO 2 , - ethanol mixture, freeze tert-butanol ambient conditions acetone 1-Methoxyheptafluoropropane. High porosities large specific surface areas achieved via supercritical, freeze- drying, while retaining original gel morphology except acetone.
