Efficient hydrazine electrochemical sensor based on PANI doped mesoporous SrTiO3 nanocomposite modified glassy carbon electrode
Herein, an electrochemical approach was developed for the rapid and selective determination of hydrazine using 5% polyaniline (PANI)-doped mesoporous SrTiO3 nanocomposite modified glassy carbon electrode (GCE). The nanocomposite was synthesized by a modified sol-gel procedure using F127 structure me...

| description | Herein, an electrochemical approach was developed for the rapid and selective determination of hydrazine using 5% polyaniline (PANI)-doped mesoporous SrTiO3 nanocomposite modified glassy carbon electrode (GCE). The nanocomposite was synthesized by a modified sol-gel procedure using F127 structure mediator agent to obtain mesoporous SrTiO3 followed by an ultra-sonication technique to produce the final PANI doped SrTiO3. Various characterization tools, namely, XRD, XPS, FE-SEM and HR-TEM confirmed the successful formation of the nanocomposite and revealed cubic perovskite structure with d-spacing value 2.70 Å for mesoporous SrTiO3. Cyclic voltammetry and electrochemical impedance spectroscopy measurements exhibited higher electrocatalytic performance of the PANI/SrTiO3 nanocomposite compared to either pure SrTiO3 or unmodified GCE. The hydrazine oxidation reaction follows the first-order diffusion-controlled kinetics with a transfer coefficient value 0.65 obtained from Tafel plot analysis. Linear sweep voltammetry (LSV) and amperometric (i-t) techniques revealed that the PANI/SrTiO3 nanocomposite modified GCE exhibited remarkable sensitivity; 0.2128 μAμM−1 cm−2 over the concentration range 0.2–3.56 mM (LSV) and 0.2438 μAμM−1 cm−2 over the concentration range 16–58 μM (amperometry) with a rapid response time |
