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。

补充资料：烧绿石(pyrochlore)
【烧绿石】(pyrochlore)又名“黄绿石”。化学成分`CaNaNb_2O_6F`。常含钽、铀等元素。等轴晶系。晶体呈八面体；通常成粒状或块状集合体。硬度5-5.5。比重4.03-4.36。半透明至不透明。树脂光泽。褐色、黄绿色或黑色，新鲜断口几乎呈黑色。条痕淡褐或淡黄色。性脆。解理平行，八面体不完全。断口贝壳装。具强放射性。常产生碱性岩、碱性伟晶岩或碳酸岩中。是提取稀土元素、铌、钽及放射性元素的矿物原料。
