Most of the ruthenium-containing compounds show useful catalytic properties. Conveniently, the catalysts are divided into those which are soluble in the homogeneous catalysts, reaction medium, and those that are not, are called heterogeneous catalysts.Ruthenium nanoparticles are formed inside the halloysite. This abundant mineral naturally contains a structure of rolled nanosheets (otherwise called nanotubes), which can support both the synthesis of Ru nanocluster and its products for subsequent usage in industrial catalysis.
