The Relationship

To improve the temperature stability, response speed and sensitivity of surface acoustic wave (SAW) gas sensor, the relationship between the sensing region of the resonator for SAW gas sensor and the sensitivity of sensor is studied, a specific resonator with big space topology structure is proposed. A SAW resonator with high temperature stability is investigated from the viewpoint of piezoelectric material, cut type and fabrication process. A nano-wire bundle based SAW gas sensor with big specific-surface-area is proposed.

Spinel Oxides

The binary mesoporous spinel oxides with high surface area have been synthesized by using KIT-6 and SBA-15 as hard templates and hydrated nitrated salts as precursors. Low temperature such as 500 °C is suitable for preparation of NiCo2O4with spinel phase. High temperature such as 800 °C is necessary for preparation of NiMn2O4, MnCo2O4, and (Co0.5Mn0.5)3O4with pure spinel phase. The prepared mesoporous spinel shows high surface area as 43-105 m2/g with pore volume as0.095-0.233 cm3/g. It is preferred to form mesoporous NiCo2O4with spherical particles.
