Synthesis of N-S Doped Graphene for Hydrogen Storage

Doping is a common and effective approach to tailor semiconductor properties. Theoretical studies predicted that doping graphene with nitrogen and sulphur can tailor its electronic properties and chemical reactivity. Hydrogen as an environment friendly fuel is a strong contender for fossil fuel based auto fuel. But the major stumbling block in realizing this is the risk involved in transporting hydrogen due to the risk of fire hazard owing to wider limits of in flammability. Hence, it is important to develop efficient hydrogen storage devices for storing and transporting hydrogen safely. Graphene in its original form do not have good hydrogen storage capacity but synthesized graphene are reported to be the best method for hydrogen storage since (Nitrogen–sulphur) doped graphene exhibit good electrical conductivity, long durability and high selectivity. CVD (Chemical vapour deposition)method is also considered one of the best method for synthesis of grapheme.
