Extended possibilities for the application of V-P oxidation catalysts
are shown, e.g, selectivite reactions and removal of harmful substance
s from waste gas. The basic physical-chemical, structure and catalytic
properties are surveyed. The effects of phase composition, defects of
crystal lattice, and acidobasicity of surface on catalytic properties
are discussed. A special attention is paid to increasing the catalyti
c activity by modifying cations.
