Heavy metals and some gases adsorption on Graphene surfaces

Abstract

Graphene applications are known worldwide in field of adsorption. The heavy and toxic metals absorptions, and as a catalyst and removal of toxic by-products are major fields of research. Unique structural properties of graphene make it a useful material as adsorbent. Different electronic properties, like partial density of states (PDOS), reveal that on doping with a cluster, the band gap of the surface decreases and the substrates start showing magnetic character. The adsorption properties of graphene make it a commendable material in surface chemistry. Electron density difference plots give insights into the adsorption behavior of heavy metals and some poisonous gases.
