BET results and band gap values of the different materials obtained in this study.
| | Sample | BET (m2/g) | Pore volume (cm3/g) | Pore size (nm) | Band gap (eV) |
| | Undoped TiO2 | 15.18 | 0.02 | 3.43 | 3.01 | | 1% Pd/TiO2 | 50.70 | 0.08 | 3.42 | 2.91 | | 3% Pd/TiO2 | 1.09 | 0.006 | 3.70 | 2.94 | | 5% Pd/TiO2 | 77.87 | 0.11 | 3.44 | 3.13 | | 1% Pt/TiO2 | 20.14 | 0.01 | 3.71 | 1.67 | | 3% Pt/TiO2 | 63.07 | 0.09 | 3.40 | 2.90 | | 5% Pt/TiO2 | 63.74 | 0.08 | 3.40 | 2.22 |
