Implementation of carbon nanomaterials into electrode networks

2 Implementation of carbon nanomaterials into electrode networks 

Graphene has also been used, owing to its high surface area providing extended contacts with Ti02 or NiO [84-91]. Intermolecular forces such as physisorption, elec-

Similar to what has been seen with CNT-doped electrodes, the presence of graphene resulted in enhanced charge transport and inhibited charge recombination. Additionally, as a consequence of doping rougher surfaces evolved, which, in turn, increased light scattering and amount of dye adsorbed onto the surface (Fig. 18.2).
