Abstract

We present a system for studying heterogeneously catalytized gas phase reactions on single-crystal surfaces. As a model reaction we studied the high-temperature dehydrogenation of methanol to formaldehyde and furtheron to CO. A new flow microreactor was developed in which a radial gas flow is run over the surface of a single-crystal sample. Residence times can be kept as short as 10−3 s opening up the same time scale as in the technical flow reactor
