Nd2O3/g-CN复合电极材料的水热合成及其在超级电容器中的应用

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 Nd 2 O 3 , (graphitic carbon nitride) g-CN, and Nd 2 O 3 /g-CN hybrid materials. The Nd 2 O 3 nanoparticles observed hexagonal structure phase was confirmed through X-ray diffraction analysis. The morphological characteristics of Nd 2 O 3 /g-CN hybrid are observed through scanning electron microscopy (SEM) which showed that the addition of g-CN in Nd 2 O 3 nanoparticle removed the agglomeration of nanoparticles, and the nanosheets morphology of g-CN enhanced the surface area. Nd 2 O 3 /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 Nd 2 O 3 /g-CN hybrid and show their suitability for use in energy storage technologies.
