| 摘 要： | 在球磨法制备镁碳储氢材料的过程中添加铝,制备了储氢材料50Mg40C10Al.用透射电子显微镜、X射线衍射和差示扫描量热分析对储氢材料的粒度、结构和教氢温度进行了测定.结果表明,球磨过程中铝不储氢;添加铝能提高铗碳储氢材料的储氢密度并降低其放氢温度,50Mg40C10Al的储氢密度达5.82%(质量分数),初始放氢温度为227.4℃.

| Abstract: | Hydrogen storage material 50Mg40C10Al is prepared by adding aluminum into the mixture of magnesium and carbon during the ball milling process.Transmission electron microscopy,X-ray diffraction and differential scanning calorimetry are used to determine the particle size,crystal structure,and dehydriding temperature of the hydrogen storage material,respectively.It is found that aluminum doesn't store H2,however,the hydrogen density of Mg/C hydrogen storage materials is increased after the addition of aluminu... |
