Efficient titanium nitride/titanium oxide (TiN/TiO 2 ) composite photoanodes have been proposed for the use not only in dye-sensitized solar cells (DSSCs) but also for water splitting. When the TiN precursor films were sintered at 500 C for 0.5 to 4 h, they were partially converted to crystalline TiO 2 containing both rutile and anatase phases. For the DSSCs, higher TiN content in the photoanodes resulted in a more negative flat-band potential and higher conductivity but lower surface area for the dye adsorption; therefore, the increase in V OC and FF but the decrease in J SC value were observed. The best DSSC, with TiN/TiO 2 composite photoanode annealed for 1 h, exhibited a power conversion efficiency of 7.27%, while the cell without TiN, i.e., the cell with a standard P25 photoanode, showed an efficiency of 7.02%. For the water splitting, higher TiN content in the photoanodes resulted in better triggering of the H 2 O electrolysis, but less photo-induced current response at UV light illumination. Considering the water splitting performance measured at AM 1.5G, the TiN/TiO 2 composite photoanode annealed for 1 h showed the best photoinduced current density (J pho ) of 0.12 mA cm À2 , as compared with that of the standard P25 film. With the TiN/TiO 2 composite photoanode annealed for 1 h, both DSSCs and water splitting electrochemical devices achieved their best performance independently.

Carbon quantum dots modified polypyrrole/titania (CQDs-PPy/TiO 2 ) nanotube hybrid was designed as supercapacitor electrode material for an energy storage. CQDs-PPy/TiO 2 was prepared by incorporating CQDs-hybridized PPy into well-aligned titania nanotube array. CQDs-PPy/TiO 2 exhibited a highly-ordered heterogeneous coaxial nanotube structure. CQDs hybridizing modification could well improve the electrical conductivity of PPy. The charge transfer resistance decreased from 22.4 mΩ cm −2 to 9.3 mΩ cm −2 and the ohmic resistance decreased from 0.817 for to 0.154 Ω cm −2 when PPy/TiO 2 was converted into CQDs-PPy/TiO 2 nanotube hybrid. The specific capacitance was accordingly enhanced from 482 F g −1 (or 161 mF cm -2 ) for PPy/TiO 2 to 849 F g −1 (or 212 mF cm -2 ) for CQDs-PPy/TiO 2 at a current density of 0.5 A g −1 . The capacitance retention was slightly increased from 78.5% to 89.3% after 2000 cycles at high current density of 20 A g −1 .The effective incorporation CQDs into PPy could simultaneously increase electrochemical capacitance and cycle stability of PPy, leading to a superior electrochemical performance. A flexible solid-state supercapacitor based on CQDs-PPy nanohybrid exhibited the stable capacitive performance at both planar and bending state. CQDs-hybridized PPy presented the promising application as supercapacitor electrode material for energy storage.
