The surface chemistry of cyclohexane (c-C{sub 6}H{sub 12}) adsorbed on the Pt(111) surface has been investigated using bismuth postdosing thermal desorption mass spectroscopy (BPTDS) and high-resolution electron energy loss spectroscopy (HREELS). Cyclohexane was found to adsorb molecularly at 95 K in agreement with others. Cyclohexane decomposition begins at {approximately} 195 K and is complete by {approximately}230 K as determined by BPTDS. Between 230 and 290 K, the dominant species on the surface are c-C{sub 6}H{sub 9,a} and H{sub a}, with small amounts of adsorbed benzene also present. The c-C{sub 6}H{sub 9,a} converts to adsorbed benzene in the temperature range 290-340 K, almost simultaneous with the desorption of H{sub a} as H{sub 2}. 25 refs., 4 figs.
