| 摘 要： | CO hydrogenation on tungsten carbides has been investigated.The methanation activitiesof tungsten carbides are comparable to that of supported Group VIII metal catalysts.Temperature-programmed thermal desorption spectra of CO on tungsten carbide show that CO is adsorbed non-dissociatively,and the surface—CO bond appears to be rather weak.

| Abstract: | CO hydrogenation on tungsten carbides has been investigated. The methanation activities of tungsten carbides are comparable to that of supported Group VIII metal catalysts. Temperature-programmed thermal desorption spectra of CO on tungsten carbide show that CO is adsorbed non-dissociatively, and the surface-CO bond appears to be rather weak. |
