Production of Flat Ceramic Membrane Contactors with a Catalytically Active Layer Based on Co3O4

Flat membrane contactors comprising ceramic disk microfiltration membranes with a deposited layer of Co3O4 are obtained. The characteristics, such as the thickness of the layer and the pore-size distribution, are determined and the specific surface of the substrate and the deposited layer of Co3O4 are determined. It is shown that the membrane contactors obtained are suitable for liquid-phase catalytic oxidation of phenols under soft conditions, including in waste waters.
