Nanoparticles of Zn–Al complex oxides (see Figure) have been successfully synthesized in large quantities using a simple hydrothermal process without a surfactant. When these nanomaterials with high surface areas are used as the catalyst for selective reduction of NO x , they show high activity, thermal/hydrothermal stability, and high selectivity to N 2 . The results indicate good potential for application of these new nanomaterials as environmental catalysts.
