摘要：

The influence of dislocation network created through the shear deformation under high pressure (Bridgman anvil) on the structural features, reactivity, structural changes, and catalytic activity of NiO samples in a CO/H-2 atmosphere was studied using TEM, XRD, and in situ XRD techniques. It was found that effect of the action depends on the initial morphology of the sample: all the parameters of the gas-solid interactions drastically changed, as well as the catalytic properties of the multiphase catalysts obtained under the treatment in the gas mixture.
