This article reviews a novel approach to design heterogeneous Ru catalysts using hydroxyapatites and hydrotalcites, and their excellent catalytic performances for aerobic alcohol oxidations, carbon-carbon bond formations, and one-pot syntheses. The catalytic systems using the above heterogeneous Ru catalysts offer significant benefits in achieving simple and clean organic syntheses. Furthermore, the present preparation method for the immobilization of metal species is much simpler than previous synthetic methods of the solid-supported transition metal catalysts, which can allow a strong protocol to create various nanostructured and functionalized heterogeneous metal catalysts.
