摘要在本章中，介绍了超临界水合成纳米粒子。超临界水特有的相行为使得有机配体的修饰成为可能，通过这种方法可以实现对颗粒大小和形貌的微调。在超临界水提供的均相还原气氛中合成金属纳米颗粒是可能的。纳米催化剂和辐射检测材料被认为是超临界水中合成的微调纳米粒子的潜在应用。此外，对超临界水中纳米粒子形成的机理研究进行了综述，包括流动反应器中粒子形成的动力学分析、用中子束显示超临界水流以及利用同步辐射X射线原位测量纳米粒子的结构形成。
Abstract In this chapter, nanoparticle synthesis using supercritical water is introduced. The characteristic phase behavior of supercritical water enables organic ligand modification, and fine tuning of particle size and morphology can be realized by the method. Synthesis of metal nanoparticles is possible in homogeneous reductive atmosphere provided in supercritical water. Nanocatalysts and radiation detection materials are presented as promising applications of the fine-tuned nanoparticles synthesized in supercritical water. In addition, mechanistic studies of nanoparticle formation in supercritical water were reviewed, including kinetics analysis of particle formation with a flow reactor, visualization of supercritical water flow with neutron beams, and in situ measurements of structural formation of nanoparticles using synchrotron X-rays.
