摘要
制备了多孔碳样品，以沸石- y为模板，在800℃下退火，以估计样品的储氢程度。通过XRD、13C MAS NMR和拉曼光谱研究，证实了多孔碳样品中只含有sp2杂化碳。测定了样品在273、223K和123K时的吸氢等温线，发现样品在123K时的最大吸氢量为1.47wt%。在较低的吸氢量下，氢与碳骨架的相互作用能为~ 10 kJ mol−1，并随着氢负荷的增加而逐渐降低。
Synthesis, characterization and hydrogen storage studies on porous carbon
Porous carbon sample has been prepared, using zeolite-Y as template followed by annealing at 800°C, with view to estimate the extent of hydrogen storage by the sample. Based on XRD, 13C MAS NMR and Raman spectroscopic studies it is confirmed that the porous Carbon sample contains only sp2 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 ∼ 10 kJ mol−1at lower hydrogen uptake and gradually decreases with increase in hydrogen loading.
