Synthesis of TiO2 Nanoparticle and its Application to Graphite Composite Electrode for Hydroxylamine Oxidation
In this work, sol-gel method was used tosynthesize titanium dioxide nanoparticles (TiO2). The TiO2nanoparticles was characterized by Scanning Electron Microscopy (SEM), x-ray diffraction (XRD) and BET technique.The TiO2 and coumarin derivative (7-(1,3-dithiolan-2-yl)-9, 10-dihydroxy-6H-benzofuro [3,...

| description | In this work, sol-gel method was used tosynthesize titanium dioxide nanoparticles (TiO2). The TiO2nanoparticles was characterized by Scanning Electron Microscopy (SEM), x-ray diffraction (XRD) and BET technique.The TiO2 and coumarin derivative (7-(1,3-dithiolan-2-yl)-9, 10-dihydroxy-6H-benzofuro [3,2-c] chromen-6-on) were incorporated in a graphite composite electrode. The resulting modified electrode displayed a good electrocatalytic activity for the oxidation of hydroxylamine, which leads to a reduction in its overpotential by more than 520 mV. Differential pulse voltammetry (DPV) of hydroxylamine at the modified electrode exhibited a linear dynamic range (between 0.5 and 500.0 µM) with a detection limit (3σ) of 0.133 μM. The high sensitivity, ease of fabrication and low cost of this modified electrode for the detection of hydroxylamine demonstrate its potential sensing applications. |
