杂原子掺杂碳材料用于氧还原反应催化剂的研究.

Oxygen reduction reaction exists in many kinds of energy storage devices, such as air cells and fuel cells. Commercial platinum carbon is usually used as the catalyst for oxygen reduction reaction. However, its disadvantages associated with high price and toxic limit its further development. Carbon based materials are considered to be the best substitute for platinum carbon catalyst, which has attracted the interest of many researchers. Due to the different physical and chemical properties of carbon atoms and heteroatoms, when the heteroatoms are incorporated into the carbon matrix, defects and active sites can be formed in the matrix, and then the conductivity and oxygen transport capacity can be improved, thereby improving the catalytic ability of carbon materials for oxygen reduction reaction. Therefore, this paper firstly introduces the mechanism of oxygen reduction reaction, and then introduces the preparation of various heteroatom doped carbon based oxygen reduction catalysts as well as their advantages and innovations.
