Abstract: The adsorption and reaction of CO and H_2O on Ni catalyst were studied using infrared spectroscopy. Some valuable results were obtained.
1. Adsorption of H_2O and CO
Two types of adsorbed CO on Ni catalyst were identified by IR spectroscopy, the linear state (2060 cm~(-1)) and bridged state (1960 cm~(-1)). Above 200 ℃, disproportionation reaction of CO could occur, forming CO_2 and surface carbon.
A wide absorption band at 3600—3100 cm~(-1) was observed when H_2O was adsorbed on the catalyst. The band belongs...
