Synthesis of Porous TiO2 Nanowires and Their Photocatalytic Properties |
| 초록 |
Abstract Porous TiO2 nanowires were obtained by a surfactant-free hydrothermal method combined with subsequent acid-washing process and calcination. FESEM analyses show that the precursor consists of a large quantity of uniform wire-like nanostructures. The nanowire-like precursors transformed to the porous nanowire products after acid-treatment and calcination at 500°C in air for 2 h. The BET surface area of the porous TiO2 nanowires can be calculated to be 86.4 m2/g. In addition, the obtained porous TiO2 nanowires were used as catalyst to photodegrade methylene blue and Rhodamine B. The results have showed that the porous TiO2 exhibit superior photocatalytic property on photocatalytic decomposition of methylene blue and Rhodamine B due to the unique porous naonstructures |
