【 摘 要 】

References(10)Cited-By(2)A metal-monolithic anodic alumina supported nickel catalyst with an interfacial NiAl2O4 layer was prepared to investigate its performance in the steam reforming of methane (SRM). Compared with commercial catalysts, this catalyst showed excellent SRM durability at 700°C. This is believed to result from the presence of the interfacial NiAl2O4 layer, which could anchor the top metallic Ni particles, and thus effectively suppress oxidation and sintering of Ni. The nickel reduced from the interfacial NiAl2O4 layer was found to be vital for SRM durability. By varying the preparation conditions of calcination temperature and impregnation sequence, a catalyst with an optimum interfacial NiAl2O4 layer was obtained. The catalyst morphologies in this study are also examined.
