The influence of dislocation network createdthrough the shear deformation under high pressure (Bridgman anvil) on the structural features, reactivity, structural changes, and catalytic activity of NiO samples is a CO/H2 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 sample: all the parameters of the gas-solid interactions drastically changes, as well as the catalytic properties of the multiphase catalysts obntained under the treatment in the gas mixture.
