Abstract
Tar reforming property was investigated for BaSnO3 catalysts with plate-like and spherical morphologies synthesized through heat treatment of co-precipitation derived BaSn(OH)6 and BaCO3/SnO2 nanocomposite precursors, respectively. The reforming test was performed at 750℃ for 3h using thermogravimetric analyzer with toluene as a model tar. Plate-like BaSnO3 showed higher catalytic activity than spherical one due to not only higher specific surface area but also exposed active crystal facets. The reforming property and coking resistance were significantly promoted under the presence of steam due to continuous release of active oxygen species from the lattice and recovery of them from the environmental steam.
