Abstract:
A new hydrogen peroxide detection sensitive material, boron doped carbonized ZIF‐67@graphene (Co‐N/C@G‐B) is synthesized through pyrolysis of a sandwich‐like ZIF‐67 coating graphene material. After doping boron atoms by using chemical vapor deposition method, new active sites such as Co 2 B and BNC bonds are created, and mesopores are significantly increased. Most importantly, this Co‐N/C@G‐B material is found to exhibit excellent performance as an enzyme‐free biosensor for detecting hydrogen peroxide with a very wide detection range (from 0.5 × 10 −6 to 60 × 10 −3 m ), a low detection limit (0.19 × 10 −6 m ), and a rapid response time (≈3 s). The prepared biosensor also shows strong anti‐interference ability in the complex working occasions. Furthermore, for real application of the materials, an electronic device of biosensor is developed by using technologies of screen printing electrode, integrated circuit, 3D printed shell, and custom‐developed program, which shows high sensitivity and portability to detect hydrogen peroxide. Such device paves a way for further practical application of advanced materials in commercial scale.
