Ja. Anderson et Mm. Khader, A HIGH-PRESSURE, HIGH-TEMPERATURE INFRARED STUDY OF CO HYDROGENATION OVER RH ZRO2/, Journal of molecular catalysis. A, Chemical, 105(3), 1996, pp. 175-183
A Rh/ZrO2 catalyst has been studied in the hydrogenation of CO in an i
n situ IR cell operating at high temperature and pressure, and using F
TIR to follow the formation of surface and gas phase species as a func
tion of reaction time. The reaction between CO and hydrogen was studie
d by varying the catalyst reduction temperature, reaction temperature,
total pressure and hydrogen/CO ratio. Surface species identified were
carbonyls on the rhodium surface, formates, carbonates and hydrocarbo
ns. The relationship between adsorbed carbonate and formate is discuss
ed in detail.
