Na nChangChina) 330031, Abstract ： Spherical nanometer CuO was employed as the core, partial of whose CuO on surface were sacrificed, which 22 reacted with HBTC ligand in solution, forming the product of CuO@HKUST-l with core-shell structure in silu. The 32 antioxidant ability of core-shell-structure CuO@HKUST-l was investigated by Otemperature programmed desorption 22 ・ (O-TPD), Htemperature programmed reduction (H2-TPR) and CO oxidation reaction The result shows that the CuO 222 ・ antioxidant ability is significantly increased The metal-organic frameworks (MOFs) HKUST-1 could protect CuO 2 fi*om oxidation because of its enrichment and slow-release of reacting gas.
