摘　　要：采用固相法制备了Ni掺杂的层状钙钛矿氧化物(NaYTi_(1-x)Ni_(x)O_(4)),通过XRD、在线质谱分析仪、FTIR等手段,表征并分析了材料的晶体结构、物化特性和稳定性。结果表明:可以使用5%的Ni取代Ti,不仅不会影响晶体结构,还可以对晶体的定向生长起到调控作用,晶格中的Ni可以在保持晶体结构稳定的前提下原位析出,同时仍具有层状钙钛矿氧化物的吸水能力、碱性和热稳定性,并较好地保留了该类化合物的高温抗硫中毒能力。Ni-doped layered perovskite oxide(NaYTi_(1-x)Ni_(x)O_(4))was prepared by solid-state method.The crystal structure,physicochemical properties and stability of NaYTi-Ni,O4 were characterized by XRD,online mass spectrometry and FTIR.The results show that:5%of Ti can be replaced by Ni,it has little effect on the crystal structure and plays a role in regulating the directional growth of crystals.Lattice Ni can be precipitated in situ on the premise of maintaining the crystal structure,while still having the water absorption capacity,alkaline and thermal stability of layered perovskite oxides.To some extent,the sulfur resistance of the compounds at high temperature was also preserved.
