Selective Oxidation of -Cymene over Mesoporous LaCoO by Introducing Oxygen Vacancies.

The liquid-phase catalytic oxidation of -cymene to 4-methylacetophenone is an industrially significant reaction. However, the targeted oxidation of a specific C-H bond of -cymene is extremely difficult due to there being many branched chains in -cymene. In here, we designed a simple method to synthesize mesoporous LaCoO catalysts with rich oxygen vacancy (O) sites.
