摘要
通过水热法制备了Zn掺杂的In_2O_3,并研究了其光催化与电化学性能.研究发现,Zn掺杂In_2O_3在紫外光下具有优异的光催化活性和稳定性,在6 h内其对亚甲基蓝溶液的催化降解率达到97.8%,并且经过3次循环催化实验后催化降解率仍能达到92%.以Zn掺杂In_2O_3作为锂离子电池阴极材料对其电化学性能进行研究,结果显示其具有优异的电化学性能,在0.1 C倍率下首次充电容量和首次放电容量分别达到926.3 mAh/g和802.9 mAh/g.
Zn doped In_2O_3 is synthesized by a hydrothermal template method. The photocatalytic and electrochemical properties of the Zn doped In_2O_3 are studied. It is found that the Zn doped In_2O_3 has a high photocatalytic activity and excellent stability under ultraviolet（UV） light irradiation. When using Zn doped In_2O_3 as photocatalyst, the degradation rate of the methylene blue（MB） is 97.8% after 6 h under UV irradiation. The degradation rate of MB still reaches 92% after three catalytic experiments cycles. The electrochemical property of the Zn doped In_2O_3 is studied by using it as the cathode material of a lithium-ion battery. It is found that the Zn doped In_2O_3 exhibits a good electrochemical property, it has an initial charge capacity of 926.3 m Ah/g and a discharge capacity of 802.9 m Ah/g when the charge-discharge rate is 0.1 C.
