摘要

Mesoporous silica KIT-6 was synthesized by a hydrothermal method and NaCl-added KIT-6 was prepared by a facile grind method. Compared with pure KIT-6, NaCl-added KIT-6 showed greatly improved humidity sensitivity. The impedance changed by more than five orders of magnitude over the whole humidity range (11-95% RH). The response time was about 47 s. Complex impedance spectra were also provided and discussed in detail to explore the humidity sensing mechanism of NaCl-added KIT-6.
