Abstract
Publisher Summary This chapter discusses the total oxidation of volatile organic compounds, with emphasis on the catalytic oxidation of toluene over CuY zeolites. Transformation of toluene in low concentration in air over CuY zeolites containing different copper contents and silicon/aluminium (Si/Al) ratios is studied at temperatures between 150 and 500°C. Total oxidation is promoted on nondealuminated catalysts and depends on the copper content. The most active catalysts correspond to the catalysts with copper (Cu) contents that are close to the complete exchange of the zeolite. The presence of sodium cocations in CuY zeolites increases their combustion efficiency, by improving the dispersion of ionic copper species and preventing the formation of cupric oxide (CuO) clusters.
