Development of a novel porous cobalt, phosphorus and nitrogen co-doped carbonaceous coating by phosphiding ZIF-67 grown on nitinol fiber for selective solid-phase microextraction of polycyclic aromatic hydrocarbons from water samples

This work presents a facile strategy for controllable transformation and fabrication of a novel porous Co–P–NC coating on NiTi wire substrate for selective preconcentration and determination of PAHs in water.
