Abstract

Methods for the production of metal–carbon nanoparticles of the core–shell type based on the formation of transition metal nanoparticles and a graphite-like shell on their surface containing to 50 graphene layers are considered. Various types of high-energy impacts or thermal transformations under exposure in a temperature range of 600–850°С were used for the synthesis of metal–carbon nanoparticles from initial metal- and carbon-containing components. Due to their unique properties, nanoparticles of this kind can be of interest as highly efficient catalysts, targeted drug carriers, contrasts in MRI diagnostics, and an element base of electronic and magnetic devices.

过渡金属纳米粒子催化形成类似石墨的壳并形成核-壳结构

摘要

考虑了基于过渡金属纳米颗粒的形成以及在其表面上包含多达50个石墨烯层的类石墨外壳的生产核-壳型金属-碳纳米颗粒的方法。在暴露于600–850°С温度范围内的各种类型的高能冲击或热转化，用于从初始的含金属和含碳组分合成金属-碳纳米颗粒。由于其独特的性质，这种纳米颗粒可以作为高效催化剂，靶向药物载体，MRI诊断的对比以及电子和磁性设备的元素库而受到关注。
