摘要：
The interaction of individual carbon oxides and their mixture with the surface of monometallic catalysts that contain iron and nickel nanoparticles was investigated for the first time by thermoprogrammed desorption. It was found that both oxides are adsorbed molecularly and dissociatively. No competition between CO and CO2 was observed upon the coadsorption of these oxides. It was shown that the preadsoption of hydrogen on the surface leads to a strengthening of the Me-CO bond, raises the activation energy of desorption, assists in the dissociative chemisorption of carbon monoxide, and leads to the appearance of hydrocarbons among the products of desorption.
