چکیده مقاله:
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 ΔHad ,ΔGad and ΔSad 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.
