This is a schematic illustration of Ni/MWCNT-based electrochemical sensor for phenol detection. Ni nanoparticles uniformly dispersed on MWCNT surface by electroless plating method provide more accessible active sites for phenol adsorption and electrooxidation; in addition, the superior conductivity of MWCNT increases electron transfer rate on electrode interface and then enhances response sensitivity. These factors endow it with high sensitivity, fast response and thus potential application for phenol detection in discharged wastewater.
