Abstract: The self-prepared mesoporous SnO2 was used as sensitive materials for the quartz resonator sensor. We have tested the gas sensitivity of the quartz resonator sensors with different fundamental frequency 8M, 12M and 16M, respectively. The results show that the toluene gas sensor based on the quartz resonator with 16M fundamental frequency has the best sensing performance, which has 250Hz response change to 2ppm toluene gas compared with clean air.
