英文摘要The effect of metal and support on ethanol oxidative steam reforming (OSR) has been investigated over a series of stable and active catalytic systems with noble (Rh or Ir) and non noble metal (Ni-Cu) supported over neutral (SiO(2)), amphoteric (Al(2)O(3)) or redox (CeO(2)) supports. Ethanol decomposition and oxidative steam reforming was investigated by in situ diffuse reflectance infrared spectroscopy under temperature-programmed desorption and surface reaction conditions. Different mechanisms were established for these systems, from the initial steps of ethanol activation to the final equilibration of the decomposition products CO, CO(2), H(2) and H(2)O. Various intermediates such as formates, acetates and/or carbonates were found to play different roles depending on the catalyst composition. The stability and activity of the investigated systems were finally assigned to specific features of these mechanisms.
