Synthesis, Characterisation and Electrochemical Studies of Co2+ Doped GdAlO3 for Sensor Applications
Journal Title: Progress in Energy & Fuels - Year 2018, Vol 7, Issue 1
Abstract
The structural and electrochemical properties of cobalt (Co2+) doped GdAlO3 nanoparticles have been investigated. Structure analysis was carried out using X-ray diffraction (XRD) and Transmission electron microscope technique (TEM). The electrochemical properties of the GdAlO3:Co2+ (3 mol %) was measured using cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS) measurements using 1 M KOH electrolyte and 1 M KOH electrolyte with 2 ml of Paracetamol. The cyclic voltammetry measurements indicate that the reversibility of the electrode reaction increases while adding 2 ml of Paracetamol. Whereas, the EIS measurements reveal that a reduction in the charge transfer resistance increases capacitance of the GdAlO3:Co2+ electrode.
