The Utz group uses surface science techniques and supersonic molecular beams to investigate the molecular mechanics of heterogeneous catalysis in model systems. Of particular interest to the group is the steam reforming of methane. This process accounts for most of the world’s hydrogen production which is used in several other commercial processes. However, methane steam reforming is a slow and harsh process. The rate-limiting step is the dissociation of CH4 to CH3 and H adsorbed on nickel. Industrial conditions exceeding 1000 K and 15 bar still provide low efficiency for product evolution. Replicating this high energy environment at controlled lab conditions helps us to understand minute details of this catalytic reaction. We systematically vary the rotational, vibrational, and translational energy of the gas and surface and measure reaction probability as a function of the system’s energy. This tunability allows us to directly test mechanistic hypotheses which will reveal new insights to current models and improve catalytic design.

We have recently implemented a Reflection Absorption Infrared Spectroscopy (RAIRS) system that allows for real-time studies of gaseous interactions on metal surfaces. We will explore preliminary data on state-resolved methane reactions on a class of reactive, isolated bi-metallic alloys known as single atom alloys to investigate further their function as a new generation of catalysts.
