Abstract
Infrared spectroscopy has been used to study the possible adsorption a nd decomposition of CO2 on a copper containing methanol catalyst. It i s demonstrated that the spectra from in situ infrared studies of the m ethanol synthesis can be complicated by many CO2 combination bands in the 2200-1900 cm(-1) region. A comparison with previously published DR IFTS spectra from studies of copper catalysts exposed to CO2 shows tha t nearly all of the bands assigned as CO adsorbed on copper originate from gas phase CO2.
