中文摘要：
借助OH^-对铝片的腐蚀作用在水溶液中制备了金属铝纳米颗粒，考察了OH^-浓度不同对产物的影响，用高分辨透射电子显微镜（HRTEM）、X-射线粉末衍射（XRD）等测试手段对产物做了表征．结果表明：通过该方法得到的铝纳米微粒是由多个铝微晶通过Al（OH）J胶凝而成，外形为类球型，颗粒大小可以通过OH^-的浓度来控制．此外，对铝纳米颗粒的形成机理进行了考察．
英文摘要：
Aluminum nanoparticles were prepared in aqueous solution by virtue of corrosion effect of OH^- on aluminum foil. The product was characterized by high resolution transmission electron microscope （HRTEM）, x-ray powder diffraction （XRD） and so on. In addition, the influence of OH^- concentration on the product was investigated. The results show that the as-prepared spherical aluminum particles are composed of several aluminum microcrystals; their size can be tuned to the different concentrations of OH^-. Finally, the presumable formation mechanism was proposed.
