Paper Abstract

The fractal structure of SiO2-ZrO2 mixed aerogel prepared for catalytic purpose is investigated using morphological statistical methods, small angle X-ray scattering and N2 adsorption-desorption measurements. These three methods provide a description of the aerogel structure over several decades. We have shown that if mixed aerogels are correctly synthesized they may present a hierarchical structure that is not very different from that of pure silica aerogels.
