First we report on stability and reactions of hydrocarbon fragments (CH2, CH3 and C2H5) on Pd(100) and supported Pd catalyst. Methods used were photoelectron and FTIR spectroscopies. CxHy fragments were produced by thermal and photo-induced dissociation of corresponding halogenated compounds. In the second part, an account is given of the decomposition of methane and its conversion into higher hydrocarbons on supported Pd. The dissociation pf CH4 on palladium occurred above 473°K to give hydrogen a small amount of ethane and surface carbonaceous species. A significant fraction of hydrogen has been dissolved into Pd crystallites. Temperature programmed reactions revealed that different kinds of surface carbon are produced by the decomposition of CH4. The effects of temperature, flow rate, methane content and support materials have also been examined.
