Abstract |
The importance of hydrogen (H2) as an alternative clean fuel has gained since the issue of global warming. The utilization of solar energy for water splitting paves a way for environmentally friendly H2 generation. Semiconductor photocatalysts facilitates the charge separation as well as surface redox reactions to improving solar-light hydrogen generation. To that end, photocatalysts comprising intimately interfaced photo absorbers and co-catalysts have gained much attention. Herein, we report the 2-D SnS2 ultrathin nanosheets integrated on 1-D CdS nanorods (CdS/SnS2) as an efficient photocatalyst for water splitting H2 generation using lactic acid as electron donor under solar light irradiation. Experimental results demonstrates that the SnS2 ultrathin nanosheets integrated CdS nanorods are show robust H2 evolution rate i.e., 20200 (μmol h−1 g−1), which is the utmost activity and nine folds higher than pristine CdS nanorods. Moreover, the as-obtained CdS/SnS2 nanohybrid show an excellent photo-stability and remained effective for 30 h under the optimal conditions. The outstanding photocatalytic activity of CdS/SnS2 reflects the promising suppression of the charge-carrier recombination rate, as determined by photoluminescence, photocurrent, and impedance analyses. |
