INFRARED SPECTROSCOPY SETUP FOR STUDYING HETEROGENEOUS CATALYTIC REACTION UNDER CONTROLLED TEMPERATURE AND PRESSURE
Fourier Transform Infrared (FTIR) spectroscopy is a well-recognized tool for
investigating material structure as well as catalytic reactivity. As FTIR
spectrometers are generally not configured to study thin films, a multi-sample
accessory for the analysis of thin films has been designed, built and tested.
Films of C-60 derivatives synthesized by electrochemical deposition were
characterized by FTIR using the multi-sample accessory.
Despite decades of research, many questions persist regarding the mechanism of
low-temperature carbon monoxide oxidation. For the study of powder catalysts,
a reaction chamber has been designed and built into the sample compartment of
the FTIR spectrometer. The chamber can be operated at low-pressures, a wide
range of temperatures, and features a gas flow design that emulates a packed
bed reactor.
