- Abstract
Deep-ultraviolet lithography has been coupled with size-reduction and nanoimprint lithography to create high-density arrays of 20-nm wide platinum nanowires supported on oxide thin films of silica, alumina, zirconia, and ceria. These nanowire arrays have been used as two-dimensional platinum model catalyst systems to study the effects of support on catalytic activity during the catalytic oxidation of carbon monoxide. Strong support dependence is seen for both reaction turnover frequency and the measured activation energy. In addition, the stability of the nanowire arrays under reaction conditions shows support dependence.
