摘　　要：六氟化硫(SF_(6))气体是电力行业广泛使用的绝缘气体,具有极强的温室效应,是二氧化碳的23500倍.但六氟化硫非常惰性,其降解与资源化利用仍然面临着极大的挑战.我们发现,在常温常压下,以α-氨基酸衍生物为反应物,六氟化硫气体为促进剂,能够通过光催化实现C—C键的偶联.研究结果表明,光催化剂反应溶剂、光照时长和底物浓度都是影响反应产率的重要因素.该研究开发了一种光催化下六氟化硫气体的有效降解与资源化利用新途径.Sulfur hexafluoride(SF_(6))is widely used in the electrical industry as insulating gas,and its global warming potential is 23 500 times of carbon dioxide(CO_(2)).However,SF_(6) is extremely inert,and its degradation and utilization are highly challenging.In this study,we have found that the SF_(6) promoted C—C bond coupling with α-amino acid derivatives as the substrates could be achieved under the conditions of photocatalysis at ambient temperature and atmospheric pressure.The studies show that solvents,reaction time and concentrations of substrates are important factors for the efficiency of the reactions.These findings showcase a new strategy for the efficiently photo-catalyzed degradation and utilization of SF_(6) gas.
