title: Synthesis of double-shelled SnO2 nano-polyhedra and their improved gas sensing properties.
abstract: A new type of non-spherical SnO2 hollow structure with double-shelled and mesoporous shells was prepared via a sacrifice template strategy in the case of SnO2, which shows high response and good selectivity to toluene.
