ABSTRACT
Nanotechnology is very useful in different sectors, including air pollution control. A variety of nanomaterials (NMs) are used as nanocatalysts, nanoadsorbent, nanofilters, and nanosensors. NMs have the property of detecting pollutants found in the air. Carbon-based nanomaterials (CNMs) sensors are used to detect harmful and toxic gases such as hydrogen sulfide and dioxides of nitrogen and sulfur. Volatile organic compounds (VOCs) are released as liquids from solids or liquids. VOCs contain a large number of chemicals, which are harmful for health and the environment. More recently, CNMs have received much attention for their use as sensors of highly efficient VOCs due to their unique physical properties and excellent electrical properties. Access to the chemical element and the surface properties of CNMs amplifies their ability to create selected sensors directing VOC gases. This chapter examines and evaluates current literature on the synthesis and use of carbon-based nanomaterials, as well as their negative effects. It is noteworthy that these nanomaterials exhibit attractive features in improving the pollution control system.
