The adsorption and decomposition of methane, ethane, and ethylene on iridium films prepared under ultrahigh vacuum was investigated. Methane adsorbed on films at 27 and 100 deg but did not decompose. Ethane decomposed on iridium (27 deg ) to hydrogen and methane and on iridium (100 deg ) to methane. The addition of oxygen to a clean iridium film greatly inhibited the subsequent decomposition of ethane to methane. Ethylene underwent self-hydrogenation to ethane on iridium (27 and 100 deg ) and methane also was produced. The roughness factor of the iridium films was about seven. (auth)
