介绍了由TiO2纳米阵列管上负载Cu2O纳米线,制备新型纳米催化剂Cu2O/TiO2 NTs的方法. 应用该新型催化剂,研究了其对卤代芳烃的C—N,C—O偶联反应的催化作用,结果表明Cu2O/TiO2 NTs不仅能很好地催化溴代芳烃与氮/氧亲核试剂的反应,而且可顺利催化氯代芳烃的反应,得到中等及优良的产率. 催化剂循环使用试验证实,催化剂在该体系中能被回收利用5次收率基本稳定.

关键词: Cu2O/TiO2催化, N-芳基化, O-芳基化, 回收利用

A novel nano-material with Cu2O nanowires loaded on TiO2 nanotubes (Cu2O/TiO2 NTs) was prepared in this paper. The new type of catalyst was used to catalyze the C—N and C—O coupling of chlorinated aromatics. The results showed that this catalyst promised the reaction of not only aryl bromide, but also aryl chloride, and most products were synthesized in good to excellent yields. Moreover, the reused experiments confirmed that the catalyst can be recycled five times and present stable yields for reaction.

Key words: Cu2O/TiO2-catalyst, N-arylation;O-arylation, recycling
