Surfactant free solution synthesis of metallic nanoclusters toward efficient use of the surfaces and their application in catalysis

在金属纳米粒子（纳米团簇）合成过程中，稳定剂的选择对于控制纳米粒子的形状、尺寸和分散稳定性是重要的。然而，纳米颗粒表面上的活性位点可能被所使用的稳定剂阻断，导致表面的低效利用。在这项研究中，无表面活性剂的解决方案为基础的方法合成金纳米簇，沿着的应用，这样的纳米粒子在catalyst. Surfactors-free合成并不意味着真正裸露的金属纳米粒子的合成，但意味着一个在没有额外的稳定剂，如硫醇盐和膦化合物，表面活性剂，和聚合物的情况下制备的金属纳米粒子。这些金属纳米颗粒通过所使用的溶剂如N，N-二甲基甲酰胺（DMF）来稳定。这项研究的结果发表在Nanotechnology Reviews（DOI：10.1515/ntrev-2012-0079）的一篇综述文章中。

The choice of stabilizer during metal nanoparticle (nanocluster) synthesis is important for controlling the shape, size, and dispersion stability of the nanoparticles. However, the active sites on the nanoparticles surfaces may be blocked by the stabilizing agents used, resulting in a less-than-effective utilization of the surfaces. In this study, surfactant-free solution-based methods of synthesizing gold nanoclusters are described, along with the applications of such nanoparticles in catalysis.Surfactant-free synthesis does not imply truly bare metal nanoparticles synthesis but implies one where the metal nanoparticles are prepared in the absence of additional stabilizing agents such as thiolate and phosphine compounds, surfactants, and polymers. These metal nanoparticles are stabilized by the solvents used such as N,N-dimethylformamide (DMF). The results developed in this study are published in a review article in Nanotechnology Reviews (DOI: 10.1515/ntrev-2012-0079).
