通过元素硫的光解反应，开发了一种对金刚石粉末表面进行硫官能团修饰的有效方法。X射线光电子能谱(XPS)、漫反射傅里叶变换红外光谱(DRIFT)和质谱分析证实了金刚石表面引入了含硫官能团。硫磺修饰的钻石粉末通过含硫的键附着在黄金表面。简而言之，将修饰后的钻石粉末暴露在金胶体中，导致金纳米粒子附着在钻石粉末上。改性后的金刚石粉在硅衬底上涂覆一层金膜，通过自组装形成硫键，实现了金刚石粉表面取向。
A useful method of modifying the surface of diamond powder with sulfur-containing functionalities was developed by the photolysis of elemental sulfur. The introduction of sulfur-containing functional groups on the diamond surfaces was confirmed by X-ray photoelectron spectroscopy (XPS), diffuse reflectance Fourier transform infrared spectroscopy (DRIFT) and mass spectroscopy analyses. The sulfur-modified diamond powder attached to gold surfaces through sulfur-containing linkages. In brief, the exposure of the modified diamond powder to a gold colloid resulted in gold nanoparticles being attached to the diamond powder. The treatment of the modified diamond powder with thin gold film on a Si substrate resulted in the alignment of surface-attached diamond powder through sulfur linkages formed by self-assembly.
