A Combined Pressure Reaction Cell – UHV Chamber With Sample Transfer System
Engineering, Chemical Engineering, Catalysis and Reaction Engineering
We have designed a high-pressurereaction cell and sample transfer system as an addition to an existing ultrahigh vacuum chamber. The system enables us to study catalyticreactions on both single crystals and polycrystalline foils over a large range of pressures from 10−4 Torr" role="presentation" style="box-sizing: border-box; display: inline; word-wrap: normal; white-space: nowrap; float: none; direction: ltr; max-width: none; max-height: none; min-width: 0px; min-height: 0px; border: 0px; padding: 0px; margin: 0px; color: rgb(51, 51, 51); font-family: Arial, sans-serif; position: relative;">10−4 Torr10−4 Torr to 1 atm. The key advantage of the setup is that the thermocouple is in direct contact with the sample, providing exact measurement of the sample temperature, while allowing transfer between two different manipulators. We demonstrate the utility of the experimental setup by monitoring oscillations in the rate of carbon monoxide oxidation over a platinum catalyst.
