Thermoelectric materials, which have the ability to convert heat into electricity, potentially could be used to capture much of the low-grade waste heat now being lost. Oxide based thermoelectric materials are many advantages for environment such as nontoxicity, thermal stability, and high oxidation resistance. Resonant X-ray scattering technique was applied for determine the charge transfer correlation in thermoelectric properties in the mixed valence oxide. The Ruddlesden-Popper structure with formula of La2−2xCa1+2xMn2O7 exhibits low thermal conductivity awing to the enhancement of phonon scattering at the interface of layer. The imprint thermoelectric modules made of oxide materials and thermoelectric power generator have been development and available for energy recovery from the waste water vapor that is discharged from the industrial waste incinerator.
