Craphene-ZnO-Au Nanocomposites for Rapid Photocatalytic Degradation of Nitrobenzene

摘要

Nitro-aromatic compounds such as nitrobenzene is indispensable to the chemical industry, as it is used in the production of various products such as soaps, metal polishes and crucially aniline. The problem with nitro aromatic compounds such as nitrobenzene are that they are highly carcinogenic and genotoxic to human beings causing diseases such as methaemoglobinaemia, which has led the Environmental Protection Agency (EPA) to set a high limit of 17 ppm (13.8 uM). It is the responsibility of chemists towards the society to find alternatives and produce greener and more sustainable chemical processes when dealing with such hazardous but important compounds.
