英文摘要The rates of CH4 adsorption on a supported Rh catalyst after different treatments of the surface were measured by means of a temporal-analysis-of-products (TAP) reactor. The catalyst was kept in a well-defined state during adsorption experiments by using a very small pulse size. CH4 adsorbs on reduced sites. The highest adsorption rate was observed with a catalyst which had undergone an oxygen treatment above 800 K. CH4 adsorption activity is strongly reduced by the complete removal of oxygen from the catalyst. The results were compared with the adsorption rates of O-2 and H2O and with the activities for C2H6 hydrogenolysis and C2H4 hydrogenation. CH4 adsorption is proposed to be structure sensitive.
