The Cu–Co mixed oxide catalysts were prepared on a La
2O
3/ZrO
2/SS support by thermal decomposition of nitrate precursors. The catalyst samples were characterized by scanning electron microscopy (SEM), X-ray photoelectron spectrum (XPS) and Brunauer–Emmet–Teller (BET) surface area. The XPS data indicated the formation of some amount of CuO together with the Cu–Co spinel after annealing at 550
°C. The Cu–Co/ZrO
2/SS thin film catalysts were tested for three-way catalytic performance and showed moderate activity.
