Enhanced supercapacitor performances using C-doped porous TiO2 electrodes

- A facile, cost-effective strategy was reported to prepare porous anatase TiO2 materials.
- C-doped porous TiO2 (C/TiO2) was in situ synthesized without the addition of carbon precursors.
- C/TiO2 manifested an enhanced capacitance than the commercial P25.
