Abstract: In order to obtain the high active catalysts for methane combustion at low temperature and good stability at high temperature, CuO/YSZ-γ-Al2O3 catalysts were prepared by sol-gel method. The effects of ZrO2 amount in carrier on the performance of CuO/YSZ-γ-Al2O3 were investigated, and the catalysts were characterized by XRD, BET and TPR techniques. The results show that the catalyst with 32.5% ZrO2 in carrier exhibits the best stability and activity. After aging at 1000 ℃ for 5h, the catalyst still has high specific surface area and better stability.
