Potential Selective H2S Adsorption onto the Graphene and Doped-Graphene Intervening layers and Reaction with Water to Evolution of Hydrogen and SO2 as a Function of Reducing Air Pollution

초록

To removal of pollutant effectively required judgement accurately to assess the known information, modification and possible alteration in adsorbents such as MOFs, composites and 2D-materials. High performance sorbents and their continuous cope of developments are extremely significant for any gaseous pollutant capture due to its increasing concentration and degradative environmental impact regarding the atmosphere. Here we developed a new possible model based on N-doped graphene’s enhanced activity to H2S adsorption capacity and selectivity. The results showed, the process is selective and specific to the H2S adsorption. Hence, we can say, the N-doped graphene could be a effective sensor for atmospheric H2S gas. Use of graphene in the purpose is cost effective but not negligible for the versatile effective nature of graphene. Furthermore, DFT calculations demonstrate the interaction of N-doped graphene pores and H2S molecules is a contributing phenomenon for an extended level of H2S uptake and selectivity.
