在本文中，新合成的纳米尺寸的碳球的高化学活性的证明。碳球可以通过在丙酮中处理来增加。吸积的机制是由于属于丙酮分子的氢原子和氧原子与分布在碳球表面的开放石墨片的边缘处的吸附的氢原子和/或氧原子的结合。碳球的高化学活性可以在催化中具有重要的应用。碳球的堆积可以显著提高使用该球制成的复合材料的强度。
In this paper, the high chemical activity of the newly synthesized nanosize carbon spheres is demonstrated. The carbon spheres can be accreted by a treatment in acetone. The mechanism for the accretion is attributed to the combination of the hydrogen and oxygen atoms belonging to the acetone molecules with the adsorbed hydrogen and/or oxygen atoms at the edges of the open graphitic flakes distributed at the surface of the carbon spheres. The high chemical activity of the carbon spheres can have important applications in catalysis. The accretion of the carbon spheres may significantly improve the strength of composite materials made using the spheres.
