Effect of shear deformation under high pressure on the reactivity and catalytic activity of nickel oxide

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.
