Abstract
The adsorption and reaction of CO, CO 2, H 2, CH 3OH, HCOOH, H 2CO, and HCOOCH 3 were studied over oxygen-treated ZrO 2. Temperature-programmed techniques were used in the presence of a flowing gas which always contained H 2. Infrared spectroscopy was used to examine the species formed upon H 2CO adsorption; oxymethylene, H 2CO 2 −, is proposed to form. Methanol formed at two temperatures, ca. 125 and 600 °C. The mechanisms for formation are discussed; low-temperature methanol formed by hydrolysis of methoxide and high-temperature methanol formed by hydrogenolysis of a methyl formate-like surface species.
