| 摘 要： | The nano ZrO2-supported copper-based catalysts for methane combustion were investigated by means of N2 adsorption, TEM, XRD, H2-TPR techniques and the test of methane oxidation. Two kinds of ZrO2 were used as support, one （ZrO2-1） was obtained from the commercial ZrO2 and the other （ZrO2-2） was issued from the thermal decomposition of zirconium nitrate. It was found that the CuO/ZrO2-2 catalyst was more active than CuO/ZrO2-1. N2 adsorption, H2-TPR and XRD measurements showed that larger surface area, better reduction property, presence of tetragonal ZrO2 and higher dispersion of active component for CuO/ZrO2-2 than that of CuO/ZrO2-1. These factors could be the dominating reasons for its higher activity for methane combustion.

| Abstract: | The nano ZrO_2-supported copper-based catalysts for methane combustion were investigated by means of N_2 adsorption,TEM, XRD,H_2-TPR techniques and the test of methane oxidation.Two kinds of ZrO_2 were used as support,one (ZrO_2-1) was obtained from the commercial ZrO_2 and the other (ZrO_2-2) was issued from the thermal decomposition of zirconium nitrate.It was found that the CuO/ZrO_2-2 catalyst was more active than CuO/ZrO_2-1.N_2 adsorption,H_2-TPR and XRD measurements showed that larger surface area,better reduction property,presence of tetragonal ZrO_2 and higher dispersion of active component for CuO/ZrO_2-2 than that of CuO/ZrO_2-1.These factors could be the dominating reasons for its higher activity for methane combustion. |
