在这里，我们报告了一种简单的克级合成四面体（Cu12Sb4S13）纳米粒子（NPs）的方法，具有高质量和良好的重现性。所得NPs具有清晰的四面体形状，平均边长约为70 nm。我们利用热压技术烧结NPs，制备用于热电测量的纳米结构球团。在675 K时，颗粒的ZT值为0.52，与非纳米结构颗粒的ZT值相当。
Here, we report a method for facile gram-scale synthesis of tetrahedrite (Cu12Sb4S13) nanoparticles (NPs) with high quality and good reproducibility. The obtained NPs had a well-defined tetrahedral shape with a mean edge length of similar to 70 nm. We sintered the NPs by the hot press technique to fabricate a nanostructured pellet for thermoelectric measurements. The figure of merit (ZT) value of the pellet was 0.52 at 675 K, which was comparable with the ZT value of the non-nanostructured counterpart.
