Progress in Research on the Noble Metal Nanoparticles Prepared by Biomass Reduction

纳米尺度的贵金属材料,因其独特的催化、电、磁和光学性能而受到广泛关注,已经成为当今纳米技术领域的一个研究热点。利用植物、微生物、动植物蛋白质、纤维素等具有还原能力的生物质还原制备贵金属纳米材料已成为一种环境友好型的制备方法。针对近年来利用不同生物质还原制备贵金属纳米颗粒的研究进展进行了综述。

The nano-scale noble metal materials had been widely concerned and become a research hotspot because of its unique catalytic, elec-tric, magnetic and optical properties. The preparation of noble metal nanomaterials by the use of biomass with reducing ability, such as plant, micro-organisms, animal and plant protein, cellulose was an environment-friendly technology. The recent progress in the research on using different biomass as reducing agents for preparing noble metal nanoparticles was reviewed.
