The unique mechanical, electrical, physical and chemical properties of carbon nanotubes (CNTs) and graphene is showing excellent detection of toxic chemicals. The graphene (GR)-Carbon nanotube (CNT) nanocomposite showed large active surface area, high porosity and electrical conductivity than graphene based or CNT based ones. The electrochemical performance of GR-CNT nanocomposite can be enhanced due to synergistic effects operating between GR and CNT. The electrochemically modified GR-CNT nanocomposites has been used in different applications such as biomedical, pharmaceutical, environmental, energy harvesting, food sector applications. This chapter summarizes the electrochemical sensing of GR-CNTs nanocomposites for detection of heavy metal ions, phenolic compounds, nitrite, nitrate, hydrogen peroxide and etc. GR-CNTs nanocomposite based electrochemical sensors showed the great selectivity, sensitivity and reproducibility for detection of environmental pollutants.
