摘要:

以Cu2O@HKUST-1(HKUST-1=Cu3(BTC)2,BTC3-=均苯三甲酸离子)线状核@壳结构为前驱体,通过在碱性条件下原位水解HKUST-1壳、氧化刻蚀Cu2O核的方法得到了一种新型的、由相互交错的CuO纳米片构筑的、中空管状的超级结构,并研究了其对CO氧化的催化活性。 结果表明,这种中空的CuO管状超级结构具有较大的比表面积(56.3 m2/g)和可观的催化活性,催化剂对CO的完全转化温度为200 ℃,190 ℃时转化效率为17.3 mmolCO/(gCuO·h)。

Abstract:

A new type of hollow tubular superstructure composed of CuO nanosheets was fabricated from Cu2O@HKUST-1(HKUST-1=Cu3(BTC)2, BTC3-=benzene-1,3,5-tricarboxylate) nanowire through the hydrolysis of HKUST-1 shell and oxidation etching of Cu2O core. The as-obtained tubular CuO superstructures possess a large Brunauer-Emmett-Teller(BET) surface area(56.3 m2/g) and exhibit high catalytic performance in CO oxidation. The complete CO conversion temperature is 200 ℃. At 190 ℃, the value of CO conversion efficiency is 17.3 mmolCO/(gCuO·h).
