✦ Synopsis

In this paper, a new type of cell for the detection of volatile products developed during CO, reduction on copper by on-line mass spectroscopy is described. Bulk copper, electrodeposited copper on glassy carbon and in situ electrodeposited copper on glassy carbon are employed as electrocatalysts. Measurements of the mass signal as function of potential or time are presented. A possible reaction mechanism of the CO, reduction on copper is discussed.
