The application of 3D printing in the designing of channel structures in monolithic catalysts dedicated to the oxidative coupling of methane

In this work, a new preparation method is proposed to obtain high temperature monolithic structures for catalytic applications. A commercial 3D printer was used to synthesise polymeric templates that were utilised in the designing of channel structures in monolithic catalysts. New materials with manganese and sodium tungstate supported on corundum with macropores of well-defined shapes and sizes were prepared; their catalytic performance was investigated in the process of the oxidative coupling of methane.
