摘要
本研究采用两步水热法将硫原位引入Bi2O3基体。合成材料的比电容为305.57 F g−1 (2 a g−1)，循环稳定性为94.12% (10 a g−1)，证明了异质结对电容和循环稳定性的增强。通过理论计算证实了内置电场的存在，突出了电极材料与离子之间的相互作用。此外，还构建了一些设备来演示其在实际应用中的实用性。本研究提出了一种原位合成异质结的有效方法，为超级电容器电极材料的发展提供了新的视角。
In situ synthesis of a Bi2O3/Bi2S3 composite heterojunction for the electrochemical characterization of supercapacitors†
This study employs a two-step hydrothermal method to in situ introduce sulfur into a Bi2O3 matrix. The synthesized material displays a specific capacitance of 305.57 F g−1 (2 A g−1) and achieves a cycling stability of 94.12% (10 A g−1), evidencing the enhancement of both capacitance and cycling stability attributed to the heterojunction. The existence of a built-in electric field was confirmed via theoretical calculations, highlighting the interactions between the electrode materials and ions. In addition, devices were constructed to demonstrate the practicality in real-world applications. This study proposes an effective methodology for the in situ synthesis of heterojunctions, offering fresh perspectives on the development of electrode materials for supercapacitors.
