Abstract

A novel voltametric sensor based on graphene-TiO2 was developed. The graphene-TiO2 nanocomposite was prepared by the hydrothermal treatment. It provides an efficient and facile approach to yield nanocomposite with TiO2 nanoparticles uniformly embedded on graphene substrate. The crystallinity and crystalline size were examined by XRD and TEM. The surface morphology of the nanocomposite is examined by SEM. The crystalline size of the as prepared nanocomposite was 17 nm. The electrochemical behaviour of paracetamol was investigated with this sensor. The graphene-TiO2 modified electrode exhibited a linear response in differential pulse voltametry, with the detection limit of 11.38 × 10-8 M.
