P2.0.3 Nanostructured Metal Oxides for High-Temperature Gas Sensing: Structural Stabilization in Porous Metal Oxides

Dominik Klaus, Michael Tiemann & Thorsten Wagner
As recently shown, nanostructured SnO2 and In2O3 prepared by nanocasting exhibit higher thermal structural stability than their non-ordered counterparts.In the presented work we will show a correlation of the thermal stability with the crystallite size of the nanostructure. In2O3is utilized as model material since preparation of nanocast phases with variable crystallite sizes is possible and it is a qualified sensing material. Two samples with different crystallite sizes but otherwise comparable structural features arethermally treated stepwise...
