摘要：

In recent years, the demand for economical multifunctional materials has increased significantly. In this paper, Co/Ni-based bimetallic-organic frameworks (Co/Ni-MOFs) materials were prepared, which showed good electrochemical recognition and oxygen evolution bifunctional activity in alkaline environment. The electrochemical test showed that the response time of the material to glucose was less than 3 s, the sensitivity was 2.0826 mu AmM-1 cm-2, and the detection limit was 8.84 mu M. The material also exhibits a good overpotential of 410 mV at a current density of 100 mA cm-2 and Tafel slope of 451 mV dec- 1. The results show that Co/Ni-MOFs can be used as an electrocatalyst for electrochemical sensors and water splitting reactions.
