A POTENTIALLY MEDIATED GREEN TECHNOLOGY TOWARDS QUANTUM DOT SENSITIZED EFFICIENT PHOTOELECTRODES FOR VISIBLE LIGHT SOLAR WATER SPLITTING |
| 초록 |
A deep eutectic solvent (DESs) has been explored as a synthetic media for Cu3SbS4 and CuSbS2 colloidal quantum dots (CQDs), decorated on NiO and TiO2 for the unassisted solar water splitting for hydrogen generation. The feasibility of the use of environmental benign solvent-based synthetic process is demonstrated herein by preparing copper antimony sulphide CQDs and their use in solar energy harvesting material for photoelectrochemical (PEC) water splitting avoiding the use of sacrificial agents. Current synthesis may promote an efficient transfer of the carriers in CQDs sensitized solar cell by avoiding a physical and energy barrier for the effective charge carriers unlike to OLA/ODE/TOP/DDT etc. mediated NCs. Corresponding CQDs modified NiO and TiO2 acts as a potentially mediated photocathode and photoanode for corrosion resistant spontaneous water splitting respectively. These new bilayered semiconductor electrodes reveals the suitable heterojunction with proper band alignment and which permits us to construct a PEC device with a TiO2 photoanode and NiO photocathode to split water effectively |
