Ni-substituted CaZrNiO_x was prepared by the homogeneous deposition method (HDP) and the effect of the preparation method on the catalytic activity was studied in dry reforming of methane. CaZrNiO_x-HDP revealed enhancements in terms of the amount of basic sites for CO₂-TPD, Ni dispersion for H₂-chemisorption, and metal-support interaction for H₂-TPR, as compared with the Ni-impregnated CaZrO_x. CaZrNiO_x-HDP exhibited better catalytic activity and stability than Ni-impregnated CaZrO_x during 100 h of reaction. The enhanced catalytic activity was related to the improved physicochemical properties, which was influenced by the preparation method.

采用均相沉积法（HDP）制备了Ni-取代的CaZrNiO _x，并研究了该制备方法对甲烷干重整过程中催化活性的影响。CaZrNiO _X -HDP揭示的增强在对CO碱性位点的量计₂ -TPD，Ni分散度用于h ₂ -chemisorption并进行H金属-载体相互作用₂ -TPR，与镍浸渍的CaZrO相比_X。CaZrNiO _x -HDP比浸渍Ni的CaZrO _x表现出更好的催化活性和稳定性在反应的100小时内。催化活性的提高与理化性质的提高有关，这受到制备方法的影响。
