摘要：
CO2 reforming of CH4 over hexaaluminates LaNi (x) Mg1-x Al11O19+delta and LaNi (x) Mg0.8Al11.2-x O19+delta were studied. XRD analysis confirmed that modifier Ni as well as Mg was inlaid into the hexaaluminate lattice. Hexaaluminate LaNi (x) Mg1-x Al11O19+delta (1.0 a parts per thousand yen x a parts per thousand yen 0.4) showed better catalytic activities and higher resistance to carbon deposition, which was attributed to their pure magnetoplumbite-type structure. For this reaction, x-value between 0.6 and 0.4 was the most suitable.
