Ozone decomposition on gold supported catalysis

摘要

A highactivity of gold-vanadia catalysts supported on titania and zirconia in the ozone decomposition has ben established.The complete catalytic benzene oxidation using ozone as oxidising agent over these catalysts shows that the reaction temperature decreasedsignificantly.The observed high activity is due to the ability of nanosized gold particles to produce active oxygen species in the contact with ozone,whichare able tooxidisebenzene atquite low temperatures.
