摘要
采用亚硫酸金钠为主盐, 在阳极氧化铝模板上进行了化学镀和电镀金实验研究。通过扫描电子显微镜和X射线衍射分析测试表明:采用以上两种方法均能制备出纳米多孔金薄膜。两种方法制备的多孔金薄膜微观结构存在较大的差异。化学镀制备的多孔金薄膜微观上是枝晶状的, 电镀制备的多孔金薄膜微观上由纳米线构成。
Abstract
Cyanide-free gold plating introducing Na3Au(SO3)2 as the gold compound is employed to prepare gold films by electroless plating and pulsed electroplating. The gold films are coated on an anodic aluminum oxide template, which is then dissolved in nitric acid solution. Scanning electron microscopy and X-ray diffraction analyses show that the gold films prepared by both methods present a porous structure. However, the difference in their microstructures is evident: the sample prepared by electroless plating possesses a dendritic structure, and that prepared by electroplating consists of nanowires.
