New-fashioned MnOx/g-C3N4@ZIF-8 catalyst for the liquid-phase selective oxidation of toluene in the absence of solvent or additives

MnO x /g-C 3 N 4 @ZIF-8 catalyst was prepared by a co-precipitation reaction. The doping of Mn and large specific surface area resulted in high catalytic activity and high target product selectivity in the liquid-phase oxidation of toluene.
