The soft nature of single wall carbon nanotube (SWCNT), single wall carbon nanohorn (SWCNH) and metal organic framework (MOF) and the important factor for clean energy storage on SWCNTs and MOFs were studied. The hydrogen adsorption capacity of various carbon materials including SWCNT and SWCNH was summarized; concentration effect of supercritical hydrogen with nanostructures of carbon is intensive to give the liquid like density of adsorbed density at 77 K. The defluorination and increase of ultramicroporosity enhance hydrogen adsorption amount at 77 K evidently. For example, the ultramicmporosity of SWCNT bundles is highly increased by HNO_3 and H_2SO_4 mixed acid treatment, giving twice of hydrogen adsorption amount. The effect of nanoscale curvature on the monolayer structure of nitrogen on the internal and external SWCNT surfaces was examined experimentally and theoretically, showing that the monolayer on the internal tube surface has a longer range ordering than that on the external surface. The radial breathing mode of SWCNT Raman spectra is sifted to a high frequency side on adsorption of alcohol molecules, showing that surface of SWCNT is very sensitive to nanoscale environments. At the same time, this effect supports softness of SWCNT wall. The SWCNH is strongly hopeful to design a high performance supercapacitor because of the single wall frame. Although new MOF showing "gate adsorption" is synthesized, the hydrogen adsorption amount at 77 K is smaller than nanostructured carbons.

研究了单壁碳纳米管（SWCNT）、单壁碳纳米角（SWCNH）和金属有机骨架（MOF）的软性，以及在SWCNTs和MOF上进行清洁储能的重要因素。综述了swcnts和SWCNH等不同碳材料的吸氢性能；超临界氢与碳纳米结构的浓度效应强烈，在77 K时产生了类似液体的吸附密度。除氟和超微孔隙度的增加明显提高了77 K时的氢吸附量。例如，HNO_3和H_2SO_4混合酸处理可显著提高swcnts束的超孔隙度，使其吸附量提高一倍。实验和理论分析了纳米尺度曲率对swcnts内外表面氮单分子层结构的影响，结果表明，管内表面的氮单分子层比外表面的氮单分子层具有更大的有序范围。吸附酒精分子时，swcnts的径向呼吸模式拉曼光谱被筛选到高频侧，表明swcnts表面对纳米尺度环境非常敏感。同时，这种效果支持了swcnts墙体的柔软性。由于采用单壁结构，SWCNH有望设计出高性能的超级电容器。虽然合成了具有“栅吸附”特性的新型MOF，但其在77 K时的氢吸附量比纳米结构碳要小。
