摘要
本研究采用溶热法合成了铜和锌掺杂的二氧化锡纳米粒子（NPs）。研究人员对合成的 NPs 进行了探究，以检测其超级电容器、光伏和磁性能。在 1 M KOH 电解液中，掺铜 SnO2 NPs 在 20 mV s-1 的条件下显示出 386 F g-1 的高比电容，作为染料敏化太阳能电池（DSSC）的对电极（CE）具有显著的催化性能，功率转换效率（PCE）达到 10.70%，与 Pt CE 相当。此外，掺杂铜的二氧化锡氮氧化物显示出最高的室温铁磁性，表明其具有磁性器件应用的潜力。我们的研究结果表明，掺杂SnO2 NPs有望成为能源和信息技术领域多功能纳米材料的候选材料。
Enhancing supercapacitor, photovoltaic and magnetic properties of SnO2 nanoparticles doped with Cu and Zn ions
In this study, Cu- and Zn-doped SnO2 nanoparticles (NPs) were synthesized by using the solvothermal method. The synthesized NPs were explored to check their supercapacitor, photovoltaic and magnetic properties. The Cu-doped SnO2 NPs showed a high specific capacitance of 386 F g−1 at 20 mV s−1 in 1 M KOH electrolyte and remarkable catalytic performance as a counter electrode (CE) for dye-sensitized solar cells (DSSCs), achieving a power conversion efficiency (PCE) of 10.70%, comparable to that of Pt CE. Moreover, Cu-doped SnO2 NPs displayed the highest room-temperature ferromagnetism, indicating their potential for magnetic device applications. Our results suggest that doped SnO2 NPs are promising candidates for multifunctional nanomaterials in energy and information technologies.
期刊介绍：
The Bulletin of Materials Science is a bi-monthly journal being published by the Indian Academy of Sciences in collaboration with the Materials Research Society of India and the Indian National Science Academy. The journal publishes original research articles, review articles and rapid communications in all areas of materials science. The journal also publishes from time to time important Conference Symposia/ Proceedings which are of interest to materials scientists. It has an International Advisory Editorial Board and an Editorial Committee. The Bulletin accords high importance to the quality of articles published and to keep at a minimum the processing time of papers submitted for publication.
