| Abstract Scope |
Thermoelectric materials have shown great potential for generating electricity from waste heat. Fabrication of nanocomposites has been proven to be a robust way of enhancing the energy conversion efficiency of thermoelectric materials. Here, we used MXene, a new generation 2D material, to synthesize the nanocomposites. Ti3C2Tx MXene has been synthesized by selective etching of Al from Ti3AlC2 MAX phase using a low-cost processing technique. Nanosized layered sheets of MXene have been incorporated as inclusions in the matrix of thermoelectric materials by the spark plasma sintering (SPS) method. Thermoelectric properties such as Seebeck coefficient, electrical and thermal conductivity of novel nanocomposites have been measured in the range from 323 to 921 K. Introduction of MXene has shown significant improvement in the thermoelectric power factor (PF), and the figure of merit (ZT) of MXene incorporated nanocomposites. Further, the transport properties have been analyzed in correlation with XRD, SEM, XPS, and Raman spectra. |
