To compare the thin-films to conventional powder catalyst, a set of specifically designed of reactor is needed, optimized for the sample geometries and the low total surface area of the samples. The smooth surface and flat geometry of the thin-films is a challenge in achieving idealized flow conditions. To circumvent this issue, recycling reactors, such as a Berty reactor has been redesigned for use with thin films. Due to their high internal circulation speed, the formation of a boundary layer and thus mass transport effects can be avoided. In addition, concepts for the use of thin films in integral reactors are being developed. To improve heat management and energy efficiency in catalysis, inductive heating is being applied and evaluated to directly heat the catalyst with precise temperature control and energy input.
