Existing fossil fuels are on the verge of extinction and thus in this scenario renewable fuels are need of hour. Hydrogen is potential energy source and can be stored in carbon materials. We propose to do inelastic neutron diffraction studies on carbon nitride material using TOSCA. This instrument TOSCA, combined with volumetric gas sorption experiments, would help to carry out the study for hydrogen storage. The materials graphitic carbon nitride and hybrid of graphene-graphitic carbon nitride were successfully synthesized and depicted good microporosity where we can store molecular hydrogen in solid state. The confinement of hydrogen molecule would be done at liquid nitrogen temperature for practical applications. We initially carried out the studies at room temperature and pressure, and the material depicted good hydrogen storage potential.
