Graphene-Metal Chalcogenide based Electrochemical Sensors for Toxic Chemicals
A. Arivarasan
The developments in industrial and technological sectors result in severe environmental issues, such as environmental contamination and pollution. Among the various types of contaminations, toxic gases, heavy metal ions, pesticides and fertilizers, etc., play a major role in environmental issues. As an advancement of the sensors used to detect such toxic chemicals, electrochemical sensor attracts much attention in recent days. The development of graphene based nanocomposites for electrochemical sensors, paving a new path for the sensitive and efficient detection of such chemicals. Graphene/metal chalcogenide based nanocomposites have gained worldwide attention in recent decades and are being researched for use in different applications due to their unique physical and chemical properties. This chapter aims a comprehensive presentation of various toxic chemicals, their environmental effects and their conventional sensing mechanism. The role of graphene, metal chalcogenides and their nanocomposites on the sensing mechanism in electrochemical sensors were reviewed.
