? 2022Transition Metal Dichalcogenides (TMDs) especially molybdenum disulfide (MoS2) benefited from its low thermal conductivity and a variety of transport behavior are highly preferred as a candidate for thermoelectric (TE) application. However, MoS2 has a low electrical conductivity that hinders the thermoelectric performance which can be overcome by several factors. In this work, we have grown MoS2 on carbon fabric (CF) and decorated it with copper oxide (CuO) using the hydrothermal method followed by the subsequent facile spray deposition method. The structural and morphological analysis confirmed the formation of pristine MoS2/CF and CuO decorated MoS2/CF. The TE properties of pristine MoS2/CF and CuO decorated MoS2/CF has been investigated from the temperature ranging from 303 to 373 K. The analysis showed that the Seebeck coefficient is gradually increasing with an increase in the concentration of CuO. The electrical conductivity, Seebeck coefficient, and power factor of the sample C3 (15 mg of CuO) is around 95.67 Sm?1, 16.5 μV/K, 0.026 μW cm?1 K?2 at 373 K, which was 4.37, 1.15, and 6.5 times higher than that of pristine MoS2/CF, respectively.
