摘要
氧还原反应存在于多种储能设备如空气电池和燃料电池的反应过程中,通常以商业铂碳作为催化剂,但铂基催化剂的高昂价格和易中毒的缺点限制了其广泛应用。碳基材料被认为是贵金属催化剂最有希望的替代物,引起了众多研究者的兴趣。这是因为某些杂原子掺杂于碳基体中会因为其与碳原子的物理化学性质的差异而在基体中形成缺陷,形成催化的活性位点,亦可提高材料的电导率和氧传输能力,从而提高了碳材料的氧还原反应催化能力。为此,本文首先介绍了氧还原反应的过程,然后介绍了多种杂原子掺杂的碳基氧还原催化剂的制备以及它们的优点和创新性。
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.
