ABSTRACT

Chemically modied graphene electrodes constitute a new class of materials that possess desired properties and are tuned toward specic analyte quantitative studies. As a result, in this chapter, we have mainly focussed on modication strategies such as covalent, noncovalent and metal nanoparticle-based routes. The covalent modication includes diazonium salt reduction, amide bond formation, polymerization, microwave irradiation and solvent-free methods like ball milling and photochemical methods. Metal nanoparticles modication of graphene includes chemical reduction, electrochemical deposition, hydrothermal, solvothermal, microwave and sonochemical routes. The applicability of chemically modied graphene toward the electrochemical quantication of selective metal ions and hydrogen peroxide sensing at trace level have been discussed.
