| Popis: | Highly mesoporous titanium carbide (TiC) based composites were synthesized through a simple carbothermal reduction of homogenous monoliths which were prepared by a one-pot sol–gel process. Their application properties as a counter electrode of dye-sensitized solar cells (DSSC) were evaluated in this paper. The surface area (116–368 m 2 /g), average particles size (14–87 nm) and pore size (4–9.2 nm) of the mesoporous composites can be easily tuned by altering chemical compositions of the precursor. Introduction of silicon into the Ti–C–O system significantly reduced the average carbide grain size and also enhanced the mesoporousity of TiC composites. The dye-sensitized solar cell using a PEDOT:PSS doped TiC–SiC–C composite as the counter electrode showed a notable efficiency of 5.7%, which doubled that of pure PEDOT:PSS cell. Potentially, the reported method could be a convenient route to fabricate porous TiC based composites for other functional applications. |
