Nano titania loaded mesoporous silica: Preparation and application as high performance humidity sensor

- TiO2/SBA-15 nanocomposite was synthesized using hydrothermal method.
- TiO2 was loaded in SBA-15 using wet impregnation and direct loading process.
- The RH sensing performance was evaluated in 11-98 RH% range.
- A fast response time (14 s) and recovery time (19 s) was observed.
- Nanocomposite shows excellent linearity, negligible hysteresis and stability.
