摘　　要：为提高Al和水的反应活性,采用高能球磨法制备了Al-Sn复合材料,通过SEM、激光粒径分析、XRD等方法表征了Al-Sn复合物的微观结构,研究了Al-Sn复合材料的水反应活性,考察了颗粒粒径、水介质、起始温度、球磨参数变化对Al-Sn复合物水反应活性的影响。实验结果表明,高能球磨法及金属Sn的加入能够大幅提高Al与水反应的活性,制备的Al-Sn复合材料与水反应的氢气产率达83.92%,快速期最大产氢速率为359mL/(min·g)。Al-Sn composite materials were prepared by high-energy ball milling method to improve the reaction activity of Al to water.The microstructure of Al-Sn composite materials was analyzed by SEM,laser particle size distribution analysis,XRD and other methods.The water reaction activity of Al-Sn composite materials was researched,and the effects of particle size,water medium,initial temperature,and ball milling parameters on the water reaction activity of Al-Sn composite materials were investigated.The experimental results show that the high-energy ball milling method and the addition of metal Sn can significantly improve the reaction activity of Al to water.The hydrogen yield of the prepared Al-Sn composite materials reacting with water reaches 83.92%,and the maximum hydrogen production rate during the rapid period is 359 mL/(min·g).
