چکیده

In this paper we experimentally worked on hydrogen storage on G-C₃N₄ in ambient temperature and 20 bar pressure. Also we determined thermodynamical properties of hydrogen adsorption. We synthesized pure G-C₃N₄ by Urea Precursor and it proved by XRD and FT-IR spectra. Results show that the pure G-C₃N₄ adsorption isotherm matched to Freundlich adsorption isotherm and ΔH_ad ,ΔG_ad and ΔS_ad obtained about (-27 kj/mol), (+21 kj/mol) and (-161 j/k) respectively. Result showed pure G-C3N4 have low hydrogen storage and could not consider as candidate for hydrogen storage materials and must equip with other materials like metal oxide, transitional metal and to promote capacity of G-C₃N₄  compounds for fuel cell application.
