“…Moreover, the vertical line in the low-frequency region along the imaginary axis (Z 00 ) signifies the conducting behaviour of the electrode material. 36 Further, the metallic conductivity of MnTiO 3 /GCE electrode and direct contact with the current collector produces a charge transfer resistance value of 19.2 Ω. These results indicates that MnTiO 3 is worthy for supercapacitor applications.…”

In this paper, we report the synthesis of MnTiO3 nanoparticles employing a simple, eco‐friendly and low‐cost hydrothermal method. The properties of MnTiO3 nanoparticles were analysed by XRD, FTIR, FE‐SEM, TEM and thermogravimetric analysis (TGA). Structural properties revealed that the MnTiO3 have rhombohedral phase. Morphological studies revealed that the synthesised sample has granular‐like structure. FTIR technique confirmed the formation of MnTiO3 nanoparticles. TGA shows that the as synthesised sample is thermally more stable. The electrochemical detection of acetaminophen (AMP) by using nano‐perovskite‐type manganese titanate (MnTiO3)‐modified glassy carbon electrode is reported. The conductive behaviour of MnTiO3‐modified glassy carbon electrode (MnTiO3/GCE) was confirmed by cyclic voltammetry (CV). Differential pulse voltammetry (DPV) was employed for the detection of AMP. DPV technique showed a comparatively lower detection potential with a higher peak response towards AMP sensing with a linear range of 1.3 to 13.8 μM. The limit of detection and sensitivity were found 1.26 μM and 36.22 μA μM−1 m−2, respectively. Moreover, the modified electrode also demonstrated better repeatability, reproducibility and higher stability, hence used for the analysis of AMP in pharmaceutical and human serum samples with good recoveries. Electrochemical properties showed that the MnTiO3 perovskite has specific capacitance 357.2 F g−1 revealing its charge storing ability.

rGO anchored copper vanadate nanostructures have been synthesized through facile hydrothermal synthesis for high efficiency energy storage applications. The prepared Cu2V2O7 and rGO@Cu2V2O7 nanostructures were fabricated as the electrode materials for three electrode and symmetrical type electrochemical supercapacitors. Based on the electrochemical analysis the electrodes show outstanding areal capacitance values of 340 and 545 F/g for Cu2V2O7 and rGO@Cu2V2O7 electrodes, respectively. Also the charge discharge curves of the rGO@Cu2V2O7 electrode revealed higher specific capacitance values of 520 F/g-1 at 1 A/g-1, which is higher than that for Cu2V2O7 electrode (318 F/g-1 at 1 A/g-1). Based on the cyclic performance, the rGO@Cu2V2O7 electrode shows 98.6% withstand even at the 1000th cycle. The symmetrical electrode based device shows a higher capacitance values of 190 F/g at 1 A/g for rGO@Cu2V2O7, which is higher than that for pure Cu2V2O7 (148 F/g at 1 A/g). The synergitic reaction of rGO@Cu2V2O7 electrode shows higher energy (29.7Wh kg-1) and power (4.8 kW kg-1) than the Cu2V2O7 and rGO@Cu2V2O7 electrodes. Also, the rGO@Cu2V2O7 symmetrical electrode device shows a higher cyclic efficiency about 97.5% at the 2000th cycle. These findings sugest that the rGO@Cu2V2O7 electrode is a promising candidate for energy storage application.
