Catalyzed CO Oxidation at 70 K on an Extended Au/Ni Surface Alloy

摘要

In 1989,Haruta et al.demonstrated that Au nanoparticles supported on transition metal oxides such as TiO_2 were active for CO oxidation at 200 K.The high reactivity of Au,surprising for a metal that had long been considered a catalytic dud,was attributed to sites that are formed along the perimeter of Au particles by interaction of Au with the transition metal of the support.
