Abstract:

Low temperature plasma belongs to a non-thermal equilibrium plasma, which has higher electron temperature and lower gas temperature. It is a new method to prepare and modify nanometer catalyst. Low-temperature plasma has attracted much attention in the preparation and modification of nano-catalytic materials because of its high efficiency, environmental protection, and easy functionalization. It exhibits outstanding advantages in the unconventional preparation, doping, manufacturing defects and vacancies of nano-catalytic materials, and thus is widely used in the preparation and modification of various catalysts. In this paper, we mainly introduced the research progress of low temperature plasma in the preparation and modification of catalysts such as oxygen reduction reaction(ORR), oxygen evolution reaction(OER), hydrogen evolution reaction(HER), fuel oxidation reaction(FOR), and the reasons for improving the performance of various catalysts were discussed. The challenges of low temperature plasma in the preparation and modification of nano-catalysts were summarized, such as relatively high cost, reactor amplification, material controllable preparation and so on. At last, the development tendency of using low temperature plasma to prepare and modify the catalyst was forecasted.

Key words: low temperature plasma, nanomaterials, preparation, modification, catalysts
