FeCl 3 -NH 2 -MIL-125(Ti) with different FeCl 3 content was prepared and characterized by XRD , SEM and XPS . The humidity sensing properties of FeCl 3 -NH 2 -MIL-125(Ti) have been investigated. Compared with NH 2 -MIL-125(Ti), FeCl 3 -NH 2 -MIL-125(Ti) was more effective in the humidity sensing. The optimal mixing ratio was FeCl 3 -NH 2 -MIL-125(Ti) (8   wt%), which exhibited the best linearity. The impedance of FeCl 3 -NH 2 -MIL-125(Ti) (8   wt%) decreases by almost three orders of magnitude in the range of 11%-95% RH. The response time and recovery time of the humidity sensor by FeCl 3 -NH 2 -MIL-125(Ti) (8   wt%) are 11   s and 86   s respectively. These results indicate the potential application of FeCl 3 -NH 2 -MIL-125(Ti) in humidity sensors.
