摘要:
Hedgehog-like titanium dioxide (TiO2) architectures composed of hundreds of one-dimensional (ID) nanorods and silver (Ag) loaded TiO2with different amounts (0.2 at%, 0.5 at% and 1 at%) were successfully prepared by facile hydrothermal process and simple isometric impregnation route. The high electron mobility of 10 nanorods on the surface of TiO2and the high porosity of Ag loaded hedgehog-like TiO2architectures enable the sensor with fast responsive and recovered properties. TiO2loaded with 0.5 at % Ag exhibited the highest response to xylene with low response/recovery time at the operating temperature of 375℃. In addition, the sensitivity and selectivity of the TiO2sensor were enhanced markedly with Ag loading.
