Fabrication of CaTiO3 modified glassy carbon electrode-based hydrogen peroxide sensor
Herein, we reported the construction of hydrogen peroxide (H2O2) sensor using calcium titanate modified screen printed electrode (CaTiO3@SPE). The CaTiO3 has been synthesized via hydrothermal method using calcium nitrate tetrahydrate and titanium butoxide as the Ca and Ti source. The CaTiO3 was characterized by many physiochemical techniques such as powder X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX), Brunauer–Emmett–Teller (BET) and scanning electron microscopy (SEM). The XRD analysis revealed the existence of decent crystalline nature in the synthesized material, while EDX results demonstrated its good phase purity. The SEM micrographs suggested that CaTiO3 has flakes-like surface structure. The BET results also indicated that CaTiO3 has specific surface area of 57.6 m2/g. Furthermore, CaTiO3 was used as the electrode material and CaTiO3@SPE has been constructed using drop-casting method. The fabricated CaTiO3@SPE was used for the sensing of H2O2 using cyclic voltammetry and linear sweep voltammetry methods. The CaTiO3@SPE exhibited reasonable limit of detection of 0.08 µM with good selectivity, stability and repeatability.
