Facile synthesis of Ag/ZIF-8@ZIF-67 as an electrochemical sensing platform for sensitive detection of halonitrophenols in drinking water

A core–shell metal–organic framework (MOF) based electrochemical sensor (Ag/ZIF-8@ZIF-67) capable of detecting 2,6-DCNP is prepared, with a broad linear response range ( R 2 = 0.992) from 240 nM to 288 μM and a low detection limit of 20 nM.
