Electroless plating is a versatile technique for the facile and controlled synthesis of metallic thin films and nanostructures. While there are numerous known procedures involving transition metals, reports on the electroless plating of post-transition metals are particularly rare, even without considering specific nanofabrication requirements. In this work we outline the development of a remarkably stable electroless plating bath for nanoscale bismuth coatings, based on the reduction of Bi-EDTA by borane dimethylamine. Its suitability for nanostructure fabrication is showcased by coating ion-track etched polycarbonate membranes, creating Bi tubes with sub-micron diameters in the process. This procedure could be particularly useful for the development and improvement of high surface-area Bi based catalysts and heavy metal sensors.
化学镀是一种用于轻松且可控地合成金属薄膜和纳米结构的通用技术。虽然有许多涉及过渡金属的已知工艺，但关于后过渡金属化学镀的报道却极为罕见，即便不考虑特定的纳米制造要求也是如此。在这项工作中，我们概述了一种用于纳米级铋涂层的非常稳定的化学镀浴的开发，该镀浴基于硼烷二甲胺对Bi-EDTA的还原反应。通过在离子径迹蚀刻的聚碳酸酯膜上镀膜展示了其在纳米结构制造中的适用性，在此过程中形成了亚微米直径的铋管。该工艺对于开发和改进高表面积铋基催化剂和重金属传感器可能特别有用。
