掺硼金刚石中硼和石墨相含量对燃料电池阴极催化性能影响
Effect of doped boron and graphite phase content of boron-doped diamonds on catalytic performance of fuel cell cathode
摘要
Abstract
Boron-doped diamonds are good candidates as metal-free catalysts for the cathodic oxygen reduction reaction of fuel cells. The relationship between the content of doped boron and sp2 hybridized graphite phase in boron-doped diamonds with the oxygen reduction reaction potential and the current density is investigated.The results show that a certain amount of boron in boron-doped diamonds has a positive effect on the catalytic activity of the oxygen reduction reaction.With the increase of boron content,the oxygen reduction reaction activity increases first and then decreases while there is no significant change in the oxygen reduction reaction potential.Catalytic sites and step atomic density are considered to play a synthetic role.Moreover,sp2 hybridized graphite phase can make the potential of the oxygen reduction reaction shift toward more positive.关键词
