以金属有机框架化合物(MOF)苯丙氨酸铜(Cu(L-Phe)2)为前体,采用一步煅烧法制备了氧化铜CuO,并对样品的微观形貌、微观结构及电化学储锂性能进行研究。结果表明,苯丙氨酸铜衍生物为直径300 nm单斜晶系的氧化铜纳米颗粒; 在100 mAh/g电流密度充/放电循环200圈后,CuO纳米颗粒负极的可逆放电比容量高达505.3 mAh/g,同时表现出良好的循环稳定性和倍率性能。

Copper oxide (CuO) was prepared by one-step calcination method using metal-organic framework (MOF) copper L-phenylalanine (Cu(L-Phe)2) as precursor. The morphology, crystal structure and electrochemical Li-storage performances of CuO were studied. The results show that Cu(L-Phe)2 derivatives are monoclinic CuO nanoparticles with a diameter of 300 nm. The reversible discharge capacity of CuO nanoparticles anode is as high as 505.3 mAh/g when cycling at 100 mAh/g for 200 cycles. Meanwhile, CuO anode also displays good cycle stability and rate performances.
