Abstract: The sources and types of typical volatile organic compounds (VOCs) are reviewed in this paper. The impact of the category of nanocatalysts and their preparation methods is discussed, and the key parameters controlling nanocatalyst performance, such as particle size, structure, and morphology, are evaluated. Current research trends on the development of supported noble- and transition-metal oxide catalysts to remove halocarbons, aromatic hydrocarbons, oxygenated organic compounds, aliphatic hydrocarbons, and nitrogen- and sulfur-containing compounds are then examined. Moreover, the effects of carbon monoxide and water vapor on the catalytic oxidation of VOCs are investigated. Finally, perspectives on the development of methods to achieve the catalytic oxidation of VOCs are presented.
