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

开发了吸氢能力大于6的活性炭。5wt%的氢被匆忙地储备在以氢燃料移动的车辆上。虽然使用金属合金的吸氢量达到2wt%，但没有出现比这种金属合金更优异的新材料，我们开发了比表面积> 2500 m^2/g的超级活性炭。虽然吸氢能力只有0. 6wt%，在室温下12 MPa下，其增加到6。5 wt%。此外，吸氢量随着1. 1 nm-微孔。总体积1. 1 nm的微孔和吸氢量表明氢气在微孔中凝聚。也就是说，氢的吸收量随着液化而跳升。此外，在本研究中开发的活性炭表明二氧化碳吸收量为0。7g/g。常温下25 MPa有地表水的活性炭吸附氢气和二氧化碳的能力低于无地表水的活性炭

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
