“…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].…”
