NiS-CoS2-Co/NC锌空气电池双功能氧电催化剂研究
NiS-CoS2-Co/NC as Bifunctional Oxygen Electrocatalyst for Rechargeable Zn-Air Batteries
摘要
Abstract
The research has successfully prepared a nitrogen-doped carbon material supported Ni and Co metal sulfides(NiS-CoS2-Co/NC)via pyrolysis of a coordination polymer of Co2+and nitrogen-containing ligands,followed by a hydrothermal reaction.The morphology,composition,and oxidation state of the prepared materials were characterized using scanning electron microscopy(SEM),X-ray diffraction(XRD),and X-ray photoelectron spectroscopy(XPS).The electrochemical testing results showed that the prepared NiS-CoS2-Co/NC material exhibited excellent ORR/OER bifunctional electrocatalysis activity and reversibility with a charge-discharge voltage difference of 0.17 V and good rate performance.Good cycling stability can achieve for 1200 cycles with discharge voltages of 1.66 V and coulombic efficiency(CE)of above 96%.The highest CE was almost 100%.关键词
