The effect of different metal oxides on the catalytic activity of a Co3O4 catalyst for toluene combustion: importance of the structure–property relationship and surface active species

Abstract

The Co–La catalyst was used to the catalytic oxidation of toluene. The LaCoO₃ perovskite was detected. The abundance of Co³⁺ and active oxygen contributed synergistically to the redox cycle reaction, which could improve the catalytic activity.
