化学家James Tour在Rice大学的实验室团队与其在中国科学院、圣安东尼奥的得克萨斯大学以及休斯敦大学的同事们一起开发了一种耐用的固态催化剂,有望取代昂贵的铂用于电解水制氢。这种新的电解催化剂是将极少量的钴以单个原子的形式分散在掺杂氮的石墨烯上(Co-NG),在超电势很低的含水介质中非常耐用,活性很高。对比试验结果表明,这种新材料几乎达到了铂的效率,能够在低起始工作电压下开始反应。新催化剂混合成溶液,可以浓 Chemist James Tour’s lab team at Rice University, along with his colleagues at the Chinese Academy of Sciences, the University of Texas at San Antonio and the University of Houston, has developed a durable solid state catalyst that is expected to replace expensive platinum for hydrogen production from electrolyzed water. This new electrolytic catalyst disperses a very small amount of cobalt as a single atom on the nitrogen-doped graphene (Co-NG), is very durable and highly active in aqueous media with very low overpotentials. The comparative test results show that this new material almost reaches the platinum efficiency and is able to start the reaction at a low initial operating voltage.
