Water is an environmentally friendly reaction medium, and the reactions in supercritical (sub-critical) water become a hot subject of current research. In-situ reaction technique, especially diamond anvil cell (DAC) and capillary which are used combining with such instruments as laser Raman, infrared spectroscopy and mass spectrograph, is one of the important methods to deeply study reaction mechanism in supercritical (sub-critical) water. In this paper, in-situ reaction techniques for looking into the reaction course in supercritical (sub-critical) water are reviewed. The structure and working principle of the diamond anvil cell , and the scope of application of DAC and capillary, as well as applications of DAC and capillary to the reaction mechanism research are introduced. At last, the prospect of in-situ reactions technique used in supercritical (sub-critical) water is discussed.
