摘　　要：以抗坏血酸和硝酸银为原料,在室温条件下合成了形貌各异的微/纳米级的金属银单质。用XRD和SEM等对合成的产物进行了表征。XRD结果表明所合成的产物具有很高的纯度和结晶度。SEM结果表明在室温条件下可合成六方形状、三角形状、多面体状的银单质。此外,在产物中还发现有少量的银微米管。考察了反应时间、抗坏血酸的用量以及表面活性剂对产物的影响。Micrometer nanometer silver particles with diverse morphologies are obtained with ascorbic acid silver nitrate as raw materials at room temperature by a solid phase synthesis method, lhe products are characterized by XRD,SEM, and so on. XRD results show that the products have high crystallinity and purity. The SEM result demon- strates that ployhedronal, hexagonal and triangular silver particles can be obtained at room termperature. Some silver microtubes are also found in the products. The effects of reaction time,mass of ascorbie acid and surfaetant on the synthesis are studicd in detail.
