摘要: 述评了三类压力下的炭化途径：分解气体自升压状态下的炭化，水热反应和还原CO₂成炭。尽管这些在加压状态下形成的不同形态和纳米织构的炭材料具有相当高的收率，然而在很多情况下它们是多种形态炭材料的混合物。述评着眼于温度-压力条件和所用的前驱体的化学组成，讨论了高纯度、分离态的炭球的形成条件。

Abstract: Carbonization under pressure was reviewed by being classified into three routes: carbonization of the precursors under pressure of their decomposition gases, carbonization under hydrothermal conditions, and reduction of pressu~rized CO₂. Carbon materials with different structures and nanotextures were formed with relatively high yield under pressure, but obtained as a mixture in most cases. In this review, the formation conditions of carbon spheres in pure and an individually separated state are discussed by focusing on the temperature-pressure conditions and the chemical composition of the precursors used.
