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

Abstract

The nature and fabrication of the fiber coatings with good adsorption capacity and selectivity play a decisive role in solid-phase microextraction (SPME). In this work, a facile strategy was proposed...

An electrochemically fabricated ZIF-67/[HOEMIM]BF4 coating for the solid-phase microextraction and detection of polycyclic aromatic hydrocarbons

“…The novel and easily operated composite coating was deposited potentiostatically in one step on a polydopamine (PDA)-modified stainless-steel wire. In contrast to the traditional solvothermal in situ growth of ZIF-67 on a substrate, 39,40 the potentiostatic method in this paper was simple to operate and took less time. Besides, it integrated the excellent adsorption performance of both ZIF-67 and [HOEMIM]BF 4 .…”

Bioinspired NC Coated BM‐ZIF for Electrochemical Monitoring of Adrenaline from Blood and Pharmaceutical Samples

“…But, ZIFs have a microporous shape and poor conductivity, which restricts active site exposure and mass transfer. To meet above challenges, new strategies have been designed in which ZIFs are linked with a variety of different conductive materials including multiwall carbon nanotubes [28], conducting polymers [2], and nitrogen-carbon (NC) coated nanomaterials [29]. Among these, NC based nanomaterials offers high conductivity, ease of synthesis and modification, high temperature resistance, cheap cost, large specific surface area, chemical stability, potential to reduce electrode fouling, allowing for a rapid electron diffusion rate and enough interface contact between the modified electrode and the electrolyte and low background current [30].…”
