1. 毕业设计(论文)的内容和要求
mgh2是一种高效水解制氢材料,采用氢化燃烧合成法(hcs)法可以合成高纯度的mgh2,但是比较耗时耗能,这是因为mg颗粒表面氧化膜的存在能够阻止氢气进入颗粒内部与镁发生氢化反应。
实验发现添加10 at.% al能够明显明显降低mg氢化所需时间,且al本事也是一种制氢材料,添加少量的al不会明显降低制氢量。
本课题采用氢化燃烧合成复合机械球磨法(hcs mm)制备的mg-10 at.% al水解制氢,为克服生成mg(oh)2致密钝化膜阻止反应充分进行的不足,拟研究mg-10 at.% al球磨处理、水解反应溶液成分和反应温度等对水解动力学性能以及水解制氢量的影响,并分析其内在机理联系。
