Our contribution demonstrates that the combination of additive manufacturing and electrophoretic deposition offers great potential for the future manufacturing of tailor-made catalytic structures for continuous flow applications. A new protocol for the controlled and homogeneous coating of both electrodes of interpenetrating porous open cell structures (interPOCS) with layers of boehmite is presented. Moreover, it has been found that by applying different coating voltages in an electrophoretic deposition (EPD) process, the properties of the obtained coating can be fine-tuned with respect to layer thickness, density, and porosity. This offers very interesting options for optimizing the catalysis-relevant properties from two sides by the use of the special interPOCS support design and by adjusting the coating through the parameters of the EPD coating process.
