Invited for this month's cover is the group of Angelika Brücker at the Leibniz Institute for Catalysis in Rostock (Germany). The cover picture shows a self‐developed stainless‐steel reaction cell for operando transmission FTIR studies of heterogeneous catalytic gas‐phase reactions at pressures up to 30 bar and temperatures up to 300°C, which is connected to a mass spectrometer for online product analysis. The performance of the cell has been tested in three types of CO 2 hydrogenation reactions (CO 2 Fischer‐Tropsch synthesis, CO 2 methanation, CO 2 conversion to dimethyl ether) on various solid catalysts implemented as self‐supporting wafers. Catalytic data obtained with this cell showed the same trends as those measured in a fixed‐bed plug‐flow reactor, thus confirming their reliability.
