The high CO oxidation activity of supported Rh nanoparticles is related to their oxidic nature. With the particle size change from >4 nm (metallic) to <2.5 nm (metal oxide) the mechanism changes from Langmuir-Hinshelwood to Mars-Van Krevelen. The support oxygen availability plays a decisive role in stabilizing these rhodium oxides.
