Increasing amount of hydrogen adsorption by adhesive layer on the activated carbon surface

加速开发吸氢量为6.5wt%的活性碳，以备与氢燃料并用的汽车上储氢。虽然金属合金的吸氢量达到了2wt%，但没有出现比这类金属合金更好的新材料。我们研制了比表面积为2500m~2/g的超高活性碳，虽然吸氢能力仅为0。在室温下12 Mpa时为6wt%，在4 Mpa时增加到6.5wt%。另外，吸氢量随1.1 nm微孔总体积的增加而增加。1.1 nm微孔的总体积与吸氢量的关系表明，氢在微孔中凝聚。也就是说，吸氢量随着液化的增加而增加。此外，本研究开发的活性碳对二氧化碳的吸收率为0。7g/g，在常温1.25 Mpa下，含地表水的活性碳吸氢、吸二氧化碳的能力低于不含地表水的活性碳

Development of the activated carbon that has an ability of the absorption of hydrogen of> 6. 5 wt% is hurried to reserve hydrogen on the vehicles which moves with hydrogen fuel. Although the hydrogen absorption amount is reached to 2wt% using the metal alloy, the new materials which is more excellent than such metal alloy does not appearWe developed super-activated carbon with a surface area of> 2500 m^2/g. Although the hydrogen absorption ability is only 0. 6 wt% under 12 MPa at room temperature, it increased to 6. 5 wt% under 4 MPa at room temperature. In addition, the amount of hydrogen absorption increased with increasing the total volume of 1. 1 nm-micro pore. The relationship between the total volume of 1. 1 nm-micro pore and the amount of hydrogen absorption suggested that hydrogen condensed in the micro pore. That is, the amount of hydrogen absorption jump up with liquefaction. Furthermore, the activated carbon developed in this study indicated carbon dioxide absorption with an amount of 0. 7g/g under 1. 25 MPa at room temperatureThe ability of hydrogen and carbon dioxide absorption of the activated carbon with surface water is lower than that of the activated carbon without surface water
