Figure 6From: Chemo-sensors development based on low-dimensional codoped Mn2O3-ZnO nanoparticles using flat-silver electrodesMechanism of 4-nitrophenol detection using doped Mn 2 O 3 -ZnO NPs coated AgE at room conditions. (a) reduction of NPs/AgE, (b) reaction of 4-nitrophenol onto the reduced NPs/AgE, (c) FESEM image of NPs, and (d) real I-V outcome for 4-nitrophenol detection with NPs/AgE.Back to article page
