The definition of nanocarbons put forward by Inagaki et al. takes into account controlling structure and texture in addition to size at the nanometer scale. It takes into account carbons with nanoscale structures and porous carbons. The most current discoveries in the subject, emphasising how surface chemistry and textural characteristics affect the performance and characteristics of catalysts, in order to set recommendations for future developments. Nanocarbons provide a number of benefits over conventional carbon materials in catalytic applications. This is due to increased electron transport as well as novel effects brought about by curvature, confinement, heteroatom doping, and better textural features. Most carbon-supported metal catalyst applications are in the pharmaceutical and fine chemical sectors. The materials that are now used are activated carbons and carbon black.
