▎ 摘　　要

NOVELTY - A boron-doped diamond (BDD) nano-array electrode based on metal-organic frameworks (MOFs) derived carbon-based template comprises porous electrode substrate, metal-organic framework-derived carbon-based array and boron-doped diamond film, from bottom to top. The boron-doped diamond film has a similar morphology to metal-organic framework-derived carbon-based arrays. USE - Boron-doped diamond nano-array electrode used in heavy metal detection. ADVANTAGE - The boron-doped diamond nano-array electrode based on metal-organic frameworks-derived carbon-based template has improves the specific surface area of the electrode, enhances the detection sensitivity of heavy metal ion. The metal-organic frameworks derivative contains a graphene-like component, can optimize the carrier transmission path of the boron-doped diamond, and obtain faster signal response speed. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of boron-doped diamond nano-array electrode based on metal-organic frameworks-derived carbon-based template.
