黄金材料的新兴工业应用

黄金作为一种宝贵的战略性资源,在稳定国民经济、抑制通货膨胀、提高国际资信、维护国家安全和防范金融风险方面具有独特的、不可替代的重要作用。近年来,随着纳米技术的扩展开发,纳米级黄金呈现出不同于大块黄金的诸多物理化学性质,从而可在工业催化、先进电子材料、光学装饰和生物医药等领域大显身手,可以说纳米技术使得黄金从左右国家金融的主要功能逐步扩展到影响国计民生的方方面面。新兴黄金纳米技术的发展日新月异,其规模化工业应用已拉开了序幕。本文综述了黄金纳米材料新兴工业应用领域的国内外进展,重点介绍了已工业化和趋于工业化的黄金纳米材料和相关技术,揭示了我国着力加强黄金工业应用研究和开发的必要性和紧迫性。

New Industrial Applications of Gold

As a preciously strategic resource,gold plays a unique and important role in stabilizing national economy,suppressing inflation,improving international trust,maintaining national safety and preventing financial risk.In recent years,nanogold exhibits many different physico-chemical properties from bulk gold with the development of nanotechnology.It can be therefore widely applied in industry catalysis,advanced electron materials,optical and decorative materials as well as biomedical materials,etc.Nanotechnology is gradually spreading the role of gold from controlling national finance to the people’s livelihood.The development of the nanogold technology is rapid and continual,and its scale industrial applications are starting.The domestic and international progresses in newly industrial applications of nanogold materials are reviewed in this paper.The industrialization of the nanogold technologies is realizing or close to realize.It reveals that R & D of industrial applications of gold in China is necessary and urgent.
