Abstract | Abstract: Nanoporous Fe_3O_4 composites containing metallic Cu nanoparticles were synthesized by reducing-leaching treatment of CuFe_2O_4 precursor. Thermoelectric properties of the composites sintere...d at 1270 ºC greatly improved compared with Fe_3O_4 without Cu, presumably due to a nanoporous structure and the Cu nanoparticles remaining in the Fe_3O_4 matrix after acid leaching. The electrical and thermal conductivity indicate that Cu in the matrix promotes the electron conduction and suppresses the phonon conduction, improving the dimensionless figure-of-merit, ZT.show more |
