A detailed introduction to specific methods and precautions for evaluating the metal dispersion of Au-supported catalysts!
Gold-supported catalysts are used in important industrial reactions such as selective oxidation, selective hydrogenation, and water-gas shift reactions, and are known to be very useful catalysts, albeit in a limited capacity. However, even when conducting metal dispersion measurements using the pulse method, which is crucial for evaluating metal-supported catalysts, CO and H2 do not adsorb at room temperature, making accurate evaluation impossible. This document discusses the specific methods and precautions for evaluating the metal dispersion of gold-supported catalysts through CO pulse measurements at low temperatures around -100°C. We encourage you to read it. 【Contents】 ■ Overview ■ Measurement ■ Summary *For more details, please refer to the PDF document or feel free to contact us.
