摘要：

Porous carbon sample has been prepared, using zeolite-Y as template followed by annealing at 800 degrees C, with view to estimate the extent of hydrogen storage by the sample. Based on XRD, C-13 MAS NMR and Raman spectroscopic studies it is confirmed that the porous Carbon sample contains only sp(2) hybridized carbon. The hydrogen sorption isotherms have been recorded for the sample at 273, 223K and 123K and the maximum hydrogen absorption capacity is found to be 1.47wt% at 123K. The interaction energy of hydrogen with the carbon framework was determined to be similar to 10 kJ mol(-1) at lower hydrogen uptake and gradually decreases with increase in hydrogen loading.
