Abstract

Nanostructured tin oxide materials with a high specific surface area and porosity are promising for applications such as electrocatalysis, lithium ion batteries or sensors. Here, we present a facile strategy for the synthesis of tin oxide aerogels using inexpensive hexahydroxostannate as tin precursor. This easy and scalable method yields tin oxide aerogels with a high specific surface area and wide pore size distribution. The method can be modified by adding hexahydroxoantimonate to obtain antimony doped tin oxide aerogels that show an electrical conductivity after annealing. A cogelation with other preformed nanoparticles (e.g. Au, Pt) leads to mixed gels. Both modifications do not have a large impact on the porous properties of the obtained aerogels. Tin oxide materials prepared via this route can be tailored to a specific application by versatile modification possibilities.
