Gold as a VOC Destruction Catalyst

3 Gold as a VOC Destruction Catalyst. - Continued research into the use of noble metal catalysts for complete oxidation reactions is required to determine the composition of catalysts most active for the process and the mechanism by which these operate. In spite of considerable research into alternative supports, varied noble metal loadings, etc., the susceptibility to deactivation of these catalysts remains a problem, particularly in the oxidation of chlorinated compounds. For this reason, alternative classes of catalysts active for VOC combustion are required. 

5% Pt/Al203 catalyst was stable for around 70 h with a lower conversion of 40% whilst the 0.5% Pd/AbOs catalyst showed a decrease in conversion from 25% conversion to zero after 25 h.
