We demonstrate a simple, low-energy method whereby tomato mosaic virus (ToMV) particles can be used to template the production of nanowires and particles consisting of alloys of gold (Au), platinum (Pt) and palladium (Pd) in various combinations. Selective nanowire growth within the inner channel of the particles was achieved using the polymeric capping agent polyvinylpyrrolidone (PVP) and the reducing agent ascorbic acid. The reaction conditions also resulted in the deposition of alloy nanoparticles on the external surface of the rods in addition to the nanowire structures within the internal cavity. The resulting materials were characterized using a variety of electron microscopic and spectroscopic techniques, which revealed both the structural and chemical composition of the alloys within the nanomaterials.
我们展示了一种简单、低能耗的方法，通过该方法，番茄花叶病毒（ToMV）颗粒可用于模板化生产由金（Au）、铂（Pt）和钯（Pd）以各种组合形成的合金构成的纳米线和颗粒。使用聚合物封端剂聚乙烯吡咯烷酮（PVP）和还原剂抗坏血酸，实现了颗粒内部通道内纳米线的选择性生长。反应条件还导致除了内腔中的纳米线结构外，合金纳米颗粒沉积在棒的外表面。使用各种电子显微镜和光谱技术对所得材料进行了表征，这些技术揭示了纳米材料中合金的结构和化学成分。
