A simple chemical particle production route to produce RuO2 nanorods is introduced.In this method, RuO2 powder is used as a precursor and air as a carried gas.In high temperature oxidizing conditions, volatile Ru oxides are decomposed to monomers which grow into nanorods.The RuO2 particles typically consisted of high aspect ratio, high surface area RuO2 nanorods having well-defined {110} facets along the needle axis.The produced particles are expected to have good catalytic activity (e.g., in oxidation reactions).
