Demonstrates improved carbon monoxide oxidation in honeycomb catalysts, indicating potential efficiency gains for air pollution reduction.
It is shown that twisting the channels of the honeycomb catalyst carrier can significantly increase its activity in carbon monoxide oxidation. The primary catalyst support based on α-Al2O3 is fabricated using a 3D-printing technology developed by the authors. A catalytically active layer is formed on the surface of the primary support by impregnation to incipient wetness using a coating suspension containing copper, cobalt, and cerium oxides; finely dispersed γ-Al2O3; boehmite; nitric acid; and water.
