| 摘 要： | A series of M-substituted hexaaluminates LaMAl11O19-δ(M=Fe, Co, Ni, Mn, and Cu) were prepared and characterized by XRD, XPS, TPR and TGA techniques, respectively. They exhibited different reducibility and catalytic activity for partial oxidation of methane (POM) to synthesis gas. Among the LaMAl11O19-δsamples, LaNiAl11O19-δshowed the best catalytic activity for the topic reaction and selectivity for synthesis gas at 780℃for 2 h. The conversion of CH4 was over 99.2%, and the product selectivity for both CO and H2 was above 90.3%. |
