Metal-organic framework-derived three-dimensional porous graphitic octahedron carbon cages-encapsulated copper nanoparticles hybrids as highly efficient enrichment material for simultaneous determination of four fluoroquinolones.

A unique 3D porous Cu@graphitic octahedron carbon cages were constructed by rapid room-temperature synthesis of a Cu-based metal-organic framework (MOF) with further pyrolysis in N2, which exhibited good enrichment ability for four fluoroquinolones (FQs) due to their superior chemical affinities to the target analytes. Applied Cu@graphitic octahedron carbon… (More)
