Nanocarbon-induced 3d–π hybridization for optimizing thermoelectric performance in Ca 2.96 Co 4 O 9
Zhen Han, Junzhan Zhang, Zhifang Zhou, Yuqing Qi, Zhongqi He, Zhiyu Cao, Ying Zhang, Fang Song, Zongmo ShiNanocarbon-induced 3d–π orbital hybridization in Ca 2.96 Co 4 O 9 composites boosted electrical conductivity, Seebeck coefficient, and strengthened phonon scattering. A high ZT value of 0.28 was obtained for the Ca 2.96 Co 4 O 9 –rGO composites at 873 K.
