The results show that well-defined La_2Zr_2O_7 powders with a single-phase pyrochlore structure can be obtained at 1100 ℃ for 3 h in air and behave excellent resistance to carbon deposition for the reaction of CO_2 reforming of methane.
结果表明,在空气中1100℃焙烧后,La-Zr-O体系催化剂形成了单相烧绿石结构复合氧化物,对CO2重整CH4制合成气反应表现出了优良的抗积炭能力,而以镍修饰后XRD方法只测量到了单相烧绿石结构La2Zr2O7衍射峰,说明NiO很有可能以无定形的细小晶粒均匀分散在La2Zr2O7表面。
