Degradation of Volatile Organic Compounds with Catalysts-Containing Zeolite and Ordered Mesoporous Silica

Abstract

This chapter will show the general concepts of catalytic systems applied to reduction of atmospheric pollutants. The catalytic oxidation of volatile organic compounds (VOCs) is considered the most efficient strategy for the degradation to CO2 and H2O using low energy costs without creating further toxic by-products. The used catalysts are noble or transition metals, which are supported on matrices with high surface area, which play a key role to decrease the amount of expensive noble metals and contribute to the performance of the catalytic system. Zeolites and ordered mesoporous silica materials are a class of porous materials extensively used as catalysts and supports due to their unique properties such as high surface area, well-defined pores, and morphological control. Here, the general approaches about catalytic oxidation of VOCs combined with zeolite and ordered mesoporous silica as supports are discussed.
