In particular, the activity of Ru catalysts has been found to be high-under mild reaction conditions, and hydrogen poisoning, a typical drawback of Ru catalysts, is satisfactorily suppressed. In this chapter, recent progress in the study of Ru catalysts supported on rare earth oxides (pure or composite oxide) is summarized with respect to their catalytic performance and physicochemical properties. As a component of oxide supports, rare earth elements with redox properties have attracted attention because of their strong electron-donating ability and high-surface area. Ru shows unparalleled activity compared to Fe, Co, and Ni under mild reaction conditions, and Ru catalysts supported on oxides are suitable for this purpose because of their high stability and ease of handling in air. From an industrial point of view, the catalyst should be easily prepared and can be handled in air. A catalyst that can produce ammonia under mild reaction conditions (below 400 ☌ and 10 MPa) is needed to achieve green ammonia synthesis using renewable energy.
