Abstract: By sol-gel combined with microwave chemical method,this research prepared the gas-sensing materials of Pr-LaFeOand made them to sintered & heater-type sensors.The testing results show that the sensor of Pr-LaFeOsynthesized from x=mol(Pr) ∶mol(Pr-LaFeO) =1∶10 is superior to others in its sensitivity to formaldehyde of 10 mL/m.In addition,the response and recovery time are about 60 s and 240 s,respectively.

Key words: microwave chemical method, Pr modified, formaldehyde gas-sensing
