In this report, copper iron sulfide nanoparticles with various composition were synthesized by a thermolysis based wet chemical method. These inherently sustainable nanoparticles were then fully characterized in terms of composition, structure, and morphology, as well as for suitability as a thermoelectric material. The merits of the material preparation include a straightforward bulk material formation where particles do not require any specialized treatment, such as spark plasma sintering or thermal heating. The Seebeck coefficient of the materials reveals P-type conductivity with a maximum value of 203 µV/K. The results give insight into how to design and create a new class of sustainable nanoparticle material for thermoelectric applications.
在本报告中，通过基于热解的湿化学方法合成了具有不同组成的硫化铜铁纳米颗粒。然后，对这些具有内在可持续性的纳米颗粒在组成、结构和形态方面进行了全面表征，并评估了其作为热电材料的适用性。材料制备的优点包括直接形成块状材料，其中颗粒不需要任何特殊处理，如放电等离子烧结或热加热。材料的塞贝克系数显示出P型导电性，最大值为203 μV/K。这些结果为如何设计和制造用于热电应用的新型可持续纳米颗粒材料提供了见解。
