NANOMETER POWDER CATALYST AND ITS PREPARTION METHOD

摘要

A composite nanometer powder catalyst containing titanium dioxide and its preparation method. This catalyst is a product prepared by the impregnating titanium-base metal ceramic compound with mixture solution containing platinum-group metal and/or non-precious metal compounds, following by drying and oxidation heat decomposing. This catalyst can be supported by platinum-group metal and/or non-precious metal to obtain another composite nanometer powder catalyst.
