摘要：
The influence of reagents interactions with V2O5 catalyst on its activity in the reaction of SO2 oxidation has been investigated by electron paramagnetic resonance (EPR) method. It was found that the deactivation of V2O5 is caused by the diminishing of the number of adsorption centers able to interact with reagent molecules and with the creation of elements of the VOSO4 phase.
