Flat membrane contactors have been obtained, which are ceramic disk micro-filtration membranes with a Co 3 O 4 layer applied. Such characteristics as the layer thickness, pore size distribution were determined, and the specific surface area of ??the substrate and the applied Co 3 O 4 layer was estimated. It has been shown that the obtained membrane contactors are suitable for carrying out liquid-phase catalytic oxidation of phenol under mild conditions, including wastewater.
