Abstract

Cu-based infinite coordination polymer nanosheets were synthesized to promote the thermoelectric performance of Bi_0.5Sb_1.5Te₃ for low-grade waste heat recovery. The diffusion of Cu into the Bi_0.5Sb_1.5Te₃ lattice increased the carrier concentration and depressed the bipolar effect. A dramatically reduced lattice thermal conductivity was obtained due to the inclusion of multiple scales scattering centers. As a result, the average zT across the temperature range of 300 ∼ 523 K reached ∼1.08. Eventually, the single-leg device based on Bi_0.5Sb_1.5Te₃/CuHT₅-365 realized an energy conversion efficiency of ∼7% at the temperature difference of 200 K.
