The present manuscript aims at the synthesis of cesium based halide perovskite nanostructures and the effect of cobalt doping on the structural, optical, lumnisent, charge storage and photocatalytic properties. In a very first attempt, we report the solvothermal synthesis of Co doped CsPbCl3 nanostructures under subcritical conditions. The structural features were demonstrated by X-ray diffraction (XRD) Surface morphology determined cubic shape of the synthesized particles. Doping is an excellent way to modify the properties of host material in particular to the electronic structure or optical properties. Incorporation of Co2+ ions in the perovskite structure tunes the optical properties of the nanostructures making this perovskite a visible light active material (Eg = 1.6 eV). This modification in the optical behaviour is the result of size effect, the crystallite size of the doped nanostructures increases with cobalt doping concentration. Photolumniscance (PL) study indicated that CsPbCl3 exhibited Blue emission. Thermogravametric analysis (TGA) revealed that the nanostructures are quite stable at elavated temperatures. The electrochemical performance depicts the pseudocapacative nature of the synthesized nanostructures and can used for charge storage devices. The charge storage capability showed direct proportionality with cobalt ion concentration. And Finally the photocatalytic performance of synthesized material shows superior catalytic ability degrading 90% of methylene blue (MB) dye in 180 min under visible light conditions.

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.
