In-Situ Charge Transport Characterization of Catalysts Using the Microwave Hall Effect Technique

One important intermediate for chemical industry is methanol, which is produced over a Cu/ZnO/Al₂O₃ catalyst from a CO/CO₂/H₂ mixture. To have a better mechanistic understanding, we analyze the influence of charge carriers participating in these redox processes on the catalytic performance using contact free electrical conductivity and Hall mobility measurements.
