摘    要:以球状纳米Cu_2O为核心,直接牺牲其表面的部分Cu_2O,与溶液中的均苯三羧酸(H_3BTC)配体反应,原位生成具有核壳结构的Cu_2O@HKUST-1材料。采用O_2程序升温脱附(O_2-TPD)、H_2程序升温还原(H2-TPR)及CO氧化反应对Cu_2O@HKUST-1核壳材料的抗氧化能力进行了研究,证明金属-有机框架材料(MOFs)HKUST-1对反应气体起到富集、缓释作用,保护Cu_2O核不被氧化,显著提高了其抗氧化能力。

关 键 词:HKUST-1  Cu2O  核壳结构  抗氧化

Abstract:Spherical nanometer Cu2O was employed as the core with partial of whose Cu2O on surface sacrificing, which reacted with benzene-1,3,5-tricarboxylic acid(H3BTC) ligand in solution, forming the product of Cu2O@HKUST-1 with core-shell structure in situ. The antioxidant ability of core-shell-structure Cu2O@HKUST-1 was investigated by O2 temperature programmed desorption (O2-TPD), H2 temperature programmed reduction (H2-TPR) and CO oxidation reaction. The result shows that the Cu2O antioxidant ability is significantly increased. The metal-organic frameworks (MOFs) HKUST-1 could protect Cu2O from oxidation because of its enrichment and slow-release of reacting gas.
Keywords:HKUST-1  Cu2O  core-shell  antioxidant capacity
