Electrophoretic deposition of ordered mesoporous carbon nitride on a stainless steel wire as a high-performance solid phase microextraction coating.

An electrophoretic deposition approach was developed to fabricate a robust ordered mesoporous carbon nitride (MCN) coating for solid-phase microextraction. The large surface area, uniform pore diameter, in-built N-rich functional groups, and electron delocalization properties of MCN make it a promising adsorbent for SPME by π-π, hydrogen bonding and hydrophobic interactions between analytes and MCN.
