In Situ Formation of a 3D Amorphous Cobalt- Borate Nanoarray: An Efficient Non-Noble Metal Catalytic Electrode for Non-Enzyme Glucose Detection
CHEMISTRYSELECT(2018)
摘要
It is highly desirable to design enzyme-free nanoarray architecture as an efficient three-dimensional (3D) catalyst electrode for sensitive and selective detection of glucose. In this communication, we report that insitu electrochemical development of an amorphous cobalt-borate nanoarray supported on carbon cloth (Co-Bi /CC) as a durable and efficient 3D nanoarray electrocatalyst for glucose detection. As a glucose sensor, Co-Bi/CC electrode shows a fast amperometric response toward glucose, a detection limit of 0.042M (S/N=3), a response sensitivity of 4191.7 mu A mM(-1) cm(-2). Importantly, it also demonstrates favourable reproducibility and long-term stability.
