Дослідження частинок на поверхні Ni-Fe каталізаторів гідрогенування СО2 методом ТД МС аналізу

The condition of Ni-Fe catalysts’ surface was investigated by the method of thermally programmed desorption with mass spectral analysis of desorbed particles (TD MS). TD spectra indicated the desorption of CO2 (m/z = 44), CO (m/z = 28) and H2O (m/z = 18) particles from the surface of samples with hi...

Description
Summary:The condition of Ni-Fe catalysts’ surface was investigated by the method of thermally programmed desorption with mass spectral analysis of desorbed particles (TD MS). TD spectra indicated the desorption of CO2 (m/z = 44), CO (m/z = 28) and H2O (m/z = 18) particles from the surface of samples with high and low catalytic activity in the reaction of CO2 hydrogenation. Intermediate compounds CHO*, CH2O* were not observed in the TD profiles for all investigated catalysts. On the basis of catalytic performance results and thermal desorption data it can be suggested that process of CO2 hydrogenation over Ni-Fe catalysts proceeds via direct hydrogenation of CO2 to CH4.
