Electrochemical analysis of Yttrium chromate nanoparticles synthesized via green mediated combustion route
Yttrium Chromate (YCrO4) nanoparticles (YCNPs) were synthesized using a solution combustion method with a green extract (NeemLeaves extract as a reducing agent. The as-obtained NPs are allowed for calcination at 600 °C. The PXRD pattern showed Bragg reflections confirming the formation of a pure te...

| description | Yttrium Chromate (YCrO4) nanoparticles (YCNPs) were synthesized using a solution combustion method with a green extract (NeemLeaves extract as a reducing agent. The as-obtained NPs are allowed for calcination at 600 °C. The PXRD pattern showed Bragg reflections confirming the formation of a pure tetragonal phase of YC NPs belonging to the space group I 41/a m d:1. without impurity peaks. The surface morphology revealed smaller, irregularly sized, and shaped NPs with pores and hollows which is the characteristic of solution combustion synthesis. UV–visible spectroscopic analysis confirmed the various absorbance peaks. The energy band gap, determined from Wood and Tauc's plot, was 3.08 eV. FTIR analysis confirmed the presence of specific functional groups in the sample. Electrochemical analysis revealed a specific capacitance range of 61.52 to 40.18 F/g within the scan range of 10 mV/s to 50 mV/s which is due to Increasing scan rate reduces specific capacitance by limiting ion diffusion into deeper pores, favoring interaction with the surface, thus decreasing utilization of active sites and overall capacitance. Collectively, these findings suggest that YCNPs hold promise for practical applications in advanced energy storage devices. |
