摘要
文中选用对羟基偶氮苯磺酸作为稳定剂和还原剂,采用湿化学方法,在室温条件下,制备出六方单晶纳米金片。场发射扫描电子显微镜、透射电子显微镜和X射线衍射的结构表征说明,产物是沿着(111)面定向生长的六方单晶金片;紫外-可见吸收光谱验证了对羟基偶氮苯化合物在制备过程中所发挥的稳定和还原双重作用。
In the paper, with a representative azo compound as the stanmzer and reducing agent, hexagonal,single-crystalline gold nano-plates were fabricated by a mild wet-chemical route under conditions of room temperature. The materials obtained were characterized by FESEM, TEM, and XRD. And the experimental results show that the product is hexagonal single-crystalline gold nano-plates with a preferential growth direction along the Au （ 111 ） plane. UV-vis absorption spectrum indicates the dual functions of the selected p-OH-ABSA, i. e. , the stabilizing and reducing properties.
