摘要：
Infrared spectra are reported of Pt/Al2O3 exposed to CO and H-2 at different conditions. Two broad bands appeared in the spectra at 2180 and 2550 cm(-1) due to the catalyst Pt/Al2O3 itself and became stronger while increasing the temperature. Adsorption of CO on Pt/Al2O3 gave an infrared band at 2085 cm-1, and when H-2 was adsorbed, methane was formed due to reaction of H-2 and the pollutant CO, while increasing the temperature, above 673 K for 1 h or so, when the pollutant CO had almost disappeared during the reaction, a band at 2060 cm(-1) appeared due to H-2 adsorption on Pt/Al2O3.
