摘要：

The interaction of hydrogen sulfide and water with a CoO/Al2O3 surface has been examined by Auger electron spectroscopy and temperature-programmed desorption. AES and TPD show that H2S decomposition occurs readily on Coo/Al2O3 at low temperature. For low H2S exposures at 140 K, no molecular water desorbs in TPD. With large exposures, hydrogen sulfide appears to react with the surface to form water, which is the only product observed. No significant amounts of hydrogen are desorbed. These results are compared with TPD of directly dosed water. © 1990.
