ABSTRACT=<p>MoS<sub>2</sub>-carbon nanofiber composites were prepared <italic>via</italic> electrospun technique with ammonium thiomolybdate(VI) and polyvinylpyrrolidone. The effects of thermal pretreatment on the morphology of material were studied. The results demonstrate that the composite nanofiber with pretreatment shows a uniform diameter and lots of small size MoS<sub>2</sub> particles inside with porous structure. When the composites was used as counter electrodes in dye-sensitized solar cell, a maximum efficiency of 5.7% has been achieved due to the combination of electrical conductivity and catalysis ability from MoS<sub>2</sub>-carbon nanofiber composites.</p>
