Platinum doped MWNT/TiO2 composite as an efficient UV-visible driven catalyst for hydrogen production |
| 초록 |
In this report, platinum nanoparticles (Pt)-doped multi-walled carbon nanotube (MWNT)/titanium dioxide (TiO2) ternary composite was synthesized by a two-step approach. In the first step, the MWNT/TiO2 composite was prepared via a sol-gel technique followed by post annealing. Finally, the Pt nanoparticles were doped by photo-reduction. This paper reports the enhanced hydrogen production through the application of Pt nanoparticles on photocatalytic water splitting under visible and UV-visible light. The results showed that no appreciable H2 production was achieved using Pt@MWNT/TiO2 ternary composites as a photocatalyst under visible light, whereas a substantial amount of H2 was produced under full spectra. The ternary composite with a Pt loading of 1.5 wt% exhibited the highest H2 production level (8718 mol g-1 h-1), which was significantly higher than that of pure TiO2 (1571 mol g-1 h-1) and MWNT/TiO2 composite (4713 mol g-1 h-1). |
