[0002] Plasma is the most common state of matter in the universe, which is different from solid, liquid and gas, and is called the fourth state of matter. Plasma contains a wide range of active substances, including free radicals, electrons, gas atoms and excited ions, in which the number of positive and negative charges is roughly equal, and the whole is electrically neutral, so it is called plasma. Plasma can be divided into hot plasma and cold plasma according to temperature. In hot plasma, the temperature of heavy particles (ions, atoms, molecules and free radicals) and electrons is similar, indicating that almost all substances are in thermal equilibrium state. Cold plasma, also known as low-temperature plasma, has a much higher electron temperature (104-105K) than heavy particles (300-1000K), and has the advantages of convenient generation, relative controllability and strong chemical activity, which has been widely studied in environmental governance.
