Synthesis and Characterization of Platinum Modified Titanium dioxide-Embedded Carbon Nanofibers for Solar Hydrogen Generation |
| 초록 |
TiO2 nanoparticles were embedded onto CNF acting as a support. The electrospinning method was adopted for fabrication of TiO2 embedded carbon nanofibers (TiO2/CNF). The photocatalytic activity of the TiO2/CNF under simulated light was improved by Pt co-catalyst photodeposition. The morphological and structural properties of TiO2/CNF and Pt photodeposited TiO2/CNF (Pt–TiO2/CNF) were investigated by FESEM, HRTEM and powder XRD techniques. The surface characteristics of these materials were investigated by XPD, photocurrent and PL measurements were also used to elaborate the effect of Pt photodeposition. The reusability and photocatalytic stability of Pt–TiO2/CNF was tested by the generation of approximately the same amounts of photocatalytic hydrogen with the same sample under the same conditions of illumination. The highest production rate of photocatalytic hydrogen generation achieved under simulated light was 3.5 μmol (after 3 hours of illumination with 0.02 g of photocatalyst). |
