Observation of Pd catalytic reactions using an in-situ gas reaction observation system that connects a transmission electron microscope (TEM) and a mass spectrometer (MS)
Introduction
By using a MEMS-Chip type sample holder, it has become possible to observe samples under conditions similar to those in which they are actually used, such as high pressure or underwater, even with general-purpose TEM. Furthermore, by combining it with gas analysis equipment such as MS, it has become possible to perform TEM observation and generated gas analysis simultaneously. In this MSTips, we will report on the reaction observation of palladium (Pd), an exhaust gas purification catalyst, by connecting JMS-Q1600GC to JEM-ARM200F equipped with an in-situ sample holder manufactured by Protochips.
