摘要

对高效和可持续的储能系统的迫切需求对高性能电极材料的开发提出了严峻的挑战。本研究通过合成一种新的g-C3N4@SnS2异质结构来解决这一差距，旨在推进超级电容器技术。该复合材料在0.8 a /g时具有787 F/g的优越比电容和56.8 Wh/kg的显著能量密度，超过了单个组件的性能。电化学阻抗谱（EIS）显示电荷转移电阻降低，表明复合材料内离子传输增强，电导率提高。前景良好的电化学特性，加上结构的完整性和稳定性，使g-C3N4@SnS2成为下一代储能设备工业应用的可行候选材料。

Synergistic enhancement of electrochemical performance in g-C3N4@SnS2 hetero-structures for advanced supercapacitor applications

The urgent demand for efficient and sustainable energy storage systems presents a critical challenge in the development of high-performance electrode materials. This study addresses this gap by synthesizing a novel g-C₃N₄@SnS₂ heterostructure aimed at advancing supercapacitor technology. The engineered composite demonstrated a superior specific capacitance of 787 F/g at 0.8 A/g and a notable energy density of 56.8 Wh/kg, surpassing the performance of its individual components. Electrochemical impedance spectroscopy (EIS) revealed a reduction in charge transfer resistance, indicating enhanced ion transport and improved conductivity within the composite. The promising electrochemical characteristics, coupled with structural integrity and stability, position g-C₃N₄@SnS₂ as a viable candidate for industrial applications in next-generation energy storage devices.

期刊介绍： DRM is a leading international journal that publishes new fundamental and applied research on all forms of diamond, the integration of diamond with other advanced materials and development of technologies exploiting diamond. The synthesis, characterization and processing of single crystal diamond, polycrystalline films, nanodiamond powders and heterostructures with other advanced materials are encouraged topics for technical and review articles. In addition to diamond, the journal publishes manuscripts on the synthesis, characterization and application of other related materials including diamond-like carbons, carbon nanotubes, graphene, and boron and carbon nitrides. Articles are sought on the chemical functionalization of diamond and related materials as well as their use in electrochemistry, energy storage and conversion, chemical and biological sensing, imaging, thermal management, photonic and quantum applications, electron emission and electronic devices. The International Conference on Diamond and Carbon Materials has evolved into the largest and most well attended forum in the field of diamond, providing a forum to showcase the latest results in the science and technology of diamond and other carbon materials such as carbon nanotubes, graphene, and diamond-like carbon. Run annually in association with Diamond and Related Materials the conference provides junior and established researchers the opportunity to exchange the latest results ranging from fundamental physical and chemical concepts to applied research focusing on the next generation carbon-based devices.
