由于每年全球消耗的能源中有一半以上被浪费为热量，因此需要高效热电材料以可靠的方式将废热转化为电能。近几十年来，纳米科学通过电子结构中的量子限制效应和热载体的晶界散射彻底改变了热电学。由于纳米材料的气相合成不容易扩展，并且固态合成在各种长度尺度的微观结构方面不可控，因此重要的研究工作集中在可以构建具有明确尺寸，组成和形态的纳米结构的溶液合成上。除了性能之外，在溶液合成的纳米材料中还发现了几种有利于便携性和成本效率的新效果。在此，对相关研究进展进行了综述，并提出了一些展望。
As more than one‐half of worldwide consumed energy is wasted as heat every year, high‐efficiency thermoelectric materials are highly demanded for the conversion of rejected heat to electricity in a reliable fashion. In the recent few decades, nanoscience has revolutionized thermoelectrics via the quantum confinement effect in electronic structures and grain‐boundary scattering of heat carriers. As the gas‐phase syntheses of nanomaterials are not easily scalable and solid‐state syntheses are not controllable in terms of microstructures at various length scales, significant research efforts have focused on solution syntheses that can build nanostructures with well‐defined size, composition, and morphology. Beyond the performance, several novel effects that benefit the portability and cost efficiency have been discovered in the solution‐synthesized nanomaterials. Herein, the relevant progress is reviewed and some prospects proposed.
