摘要

掺杂金属离子可调控复合金属氧化物中活性金属的配位环境并构造缺陷位，进而提高复合金属氧化物作为催化剂催化性能。利用溶胶凝胶法制备了掺杂Zn、Ce或Fe的Ni基复合氧化物催化剂，并用于催化甲烷部分氧化（POM）反应。采用XRD、N

物理吸/脱附、H

-TPR和XPS等方法对催化剂晶相结构、织构性质、还原性能和物种化学状态等进行了表征。结果表明，金属离子掺杂有效调控了Ni和活性氧物种的分布，其中，Ni

0.24

催化剂中Ce的掺杂增强了Ni与其他金属的相互作用，增大了催化剂表面活性氧物种数量，该催化剂在高温段（550~600 ℃）的H

Abstract

Doping metal ions can regulate the coordination environment and construct structural defect sites of active metals in the composite metal oxides

and then improve the catalytic performances of composite metal oxides as catalysts. Ni-based composite oxide catalysts by doping Zn

Ce or Fe were prepared by sol-gel method and used in catalyzing partial oxidation of methane (POM) reaction. The crystal structures

structure properties

reduction performances and species chemical states of catalysts were characterized by XRD

physical adsorption/desorption

-TPR and XPS and so on. The results show that doping metal ions effectively regulates the distribution of Ni and reactive oxygen species. Among them

doping Ce in Ni

0.76

0.24

catalyst enhances the interaction force between Ni and other metals

increases the number of reactive oxygen species on the catalyst surface. The H

selectivity achieves nearly 100% at the high temperature stage (550 ℃ to 600 ℃).
