β¦ Synopsis
Mechanical treatment of V,O, or V-P-O catalysts causes a substantial increase of both catalytic activity in n-butane oxidation and the selectivity to maleic anyhydride. Changes in specific surface area and anisotropic deformation take place. Mechanochemical treatment of the initial reagent impairs such properties that they remarkably influence the catalytic properties of the final catalyst.
