Hydrothermal synthesis of MnO2 nanorods for efficient electrochemical detection of environmental anthropogenic pollutants and nitrobenzene

Glassy carbon (GC) electrodes are fabricated with nanoscale manganese dioxide (MnO2) rods for efficient detection of the toxic anthropogenic pollutant and nitrobenzene (NB) in real water. The MnO2 nanorods were prepared using a hydrothermal method. Its structure and morphology were characterized by...
