Nanomaterials (NMs) are the building units for advanced science and technol- ogy. The high surface area and porosity of the NMs excel its properties in many folds compared to the bulk counterpart. NMs allow easy functionalization of surface, tailoring the electronic properties, conductivity, catalytic property, and response to physical events. The functionalization of NMs allows inclusion of functional groups and species over the surface, resulting to an improved structure with novel characteristics. As compared to homogeneous catalyst, heterogeneous catalyst has shown emerging performance in the various chemical reactions due to synergistic effect developed from intimate contact between different elements incorporated. In this chapter, various fabrication techniques such as co-precipitation, impregnation, ion-exchange, immobilization, sol-gel, chemical vapor deposition, hydrothermal, microemulsion, and thermal decomposition methods used to synthesize functionalized NMs have been briefly discussed. The characteristic features of carbon-based materials and their functionaliza- tion technique such as covalent and noncovalent functionalization based on the π-conjugation system or force of attraction are emphasized. This chapter also discusses various functionalized based materials such as Pd, Pt, Ag, graphene, carbon nanotubes, biomaterials, and metal oxides and their usefulness in influ- encing the catalytic performance with examples.
