TL;DR: In this paper, the role of oxygen vacancy defects in the activation-oxidation process of toluene was investigated, and the as-prepared MnOx-ET catalyst has more surficial oxygen vacancies and good oxygen storage capacity.

TL;DR: In this paper, a series of MnOx-CeO2 catalysts with various Mn/(Mn+Ce) molar ratios were synthesized with citric acid complex method for O-vacancy study in soot catalytic combustion.

TL;DR: In this paper, the size effect of Pt nanoparticles on the activity of Pt/CeO2 catalysts toward catalytic oxidation of toluene was elucidated, and three types of TOF values based on Pt dispersion, oxygen vacancy concentration and both of them were calculated respectively, and the result demonstrates that the reaction rate is controlled by both of the exposed Pt atom and oxygen vacancies.

TL;DR: In this article, the shape effect of Pt/CeO2 catalysts toward catalytic oxidation of toluene was elucidated, and two types of TOFs based on the Pt dispersion and the concentration of surface oxygen vacancies were calculated, and the results suggest the oxygen vacancies on ceria surface control the reaction rate.

TL;DR: In this paper, three-dimensional hierarchical Co3O4 nanocatalysts with different morphologies and various exposed crystal planes were synthesized via a hydrothermal process without the use of a cobalt surfactant precursor and subsequent direct thermal decomposition.
