Stimulation in fullerene for adsorbing pollutant gases: A review

Abstract

The catalytic activities of fullerene are affected largely by different shapes and surface arrangements influencing catalyst activity and stability a lot. Surface structures of metal oxides (MOs) adsorbed on surfaces of C60-fullerene can show gas sensing properties. Greenhouse gases can be captured and stored on those surfaces. Adsorption of gases on the MOC60 complex is more effective than the direct adsorption of gases on fullerene only. The possibility of morphological structures has been considered in the paper for adsorption of gases like NO2, CO, CO2, N2O on the surface of MO-[60] fullerene. Cu2O, ZnO and NiO metal oxides (MOs) when exposed to [60] fullerene at different sites between rings, MOs occupy different positions. The formation of quasi- rings provides extra stability to the adsorbed molecules thereby helping towards the greener and cleaner environment. In this review we have summarized the more effective adsorption of gases on MO- C60 surface as compared to that of direct adsorption. The morphological changes in the structures are predicted furthermore.
