摘　　要：贵金属纳米线网具有较高的比表面积和电催化活性，是一类在传感器、光学材料、催化剂及生物领域都有着广阔应用前景的新型材料。纳米材料的直径和形貌控制有利于提高贵金属的利用率，并降低使用成本。本文研究了常温下使用氯金酸、柠檬酸钠和硼氢化钠的混合体系制备具有延展性好、直径均一的金纳米线网，并对其进行了表征。Noble metal nano--wire networks are an important new materials that has foresight development due to their higher surface area and electroactive surface area. Such materials have wide applications in such areas as sensors,optical materials , catalysis and biology. The manipulation of the diameter and shape of gold materials at the nanoscale can contribute to lowering noble metal usage and achieving the necessary cost reduction. The article reviews a method used to produce extended well - formed and uniform relatively gold nano-- wire networks using auric chloride acid, sodium citrate and sodium borohydride at room temperature.
