Abstract
The method to determine the decomposition starting temperature of hydr ocarbons adsorbed on a single crystal surface was developed by taking use of inhibiting effect of CO on decomposition. The representative re sults for cycloheptane decomposition on Ni(755) have been presented. T emperature programmed desorption (TPD) spectra after preflash and post dosing of CO indicated that the decomposition of adsorbed cycloheptane to partially dehydrogenated intermediates started at 162 K and was co mpleted by 200 K. The characteristics and differences in predosing and postdosing effects between CO and bismuth have been discussed.
