Cover Story: Copper-based mixed metal oxides derived from calcination of hydrotalcite-like materials were tested as catalysts of selective catalytic oxidation of ammonia to dinitrogen. Obtained results allow correlating redox properties, phase composition, and the CuO particle size with the catalytic efficiency of materials.View this paper.
