Hydrothermal synthesis of Nd2O3/g-CN hybrid electrode material hybrid supercapacitor applications

The exhaustion of fossil fuels and its harmful effects on human health demand the development of alternate sources for energy generation such as supercapacitors (SC_s) as useful resources for energy storage with high-power delivery. This study reports a straightforward hydrothermal route for the synthesis of Nd₂O₃, (graphitic carbon nitride) g-CN, and Nd₂O₃/g-CN hybrid materials. The Nd₂O₃ nanoparticles observed hexagonal structure phase was confirmed through X-ray diffraction analysis. The morphological characteristics of Nd₂O₃/g-CN hybrid are observed through scanning electron microscopy (SEM) which showed that the addition of g-CN in Nd₂O₃ nanoparticle removed the agglomeration of nanoparticles, and the nanosheets morphology of g-CN enhanced the surface area. Nd₂O₃/g-CN hybrid demonstrated specific capacitance (C_sp) of 960 F/g at 1 A/g ( for the prepared nanohybrid structure, which showed stability even after 5000 cycles. The results confirm the exceptional electrochemical properties of Nd₂O₃/g-CN hybrid and show their suitability for use in energy storage technologies.
