Graphene functionalized with polyaniline can be used as a high-performance flexible electrode. The gravimetric and volumetric capacitances of the hybrid reach 233 F g1 and 135 F cm 3 respectively, more than those of graphene paper (147 Fg-1 and 64 F cm 3) [90],...

Further, due to its unique 2D flexible structure and extremely high carrier mobility, graphene has proven to be an attractive material as well as good promoter for electron transportation. In DSSCs, the expensive Pt-based counter electrode has to be replaced by low-cost materials and highly conductive carbon-based materials are promising candidates. Recently researchers have reported that the performance of graphene functionalized...

In 2007, Novoselov and co-workers first demonstrated the application of pristine graphene as a sensor for room-temperature detection of NH3, NO2, and CO. ° Subsequently, Kern and co-workers functionalized graphene with palladium nanoparticles to impart sensitivity towards hydrogen. Currently, there are not many reports in the literature for detectiOTi of VOCs by pristine graphene. However, graphene functionalized with ZnO ° and Sn02 nanoparticles and GO functionalized with polypyrene have been reported for rapid and sensitive detection of formaldehyde, propanal, and toluene, respectively (Table 14.3).
