A Ce0.4Zr0.6O2 washcoat was prepared using an impregnation method, which acted as a host for the active Pd component to prepare a Pd-Ce0.4Zr0.6O2/substrate monolithic catalyst for toluene combustion.The catalyst was characterized by scanning electron microscopy (SEM), Raman spectroscopy, Brunauner-Emmett-Teller (BET), and carbon monoxide temperature-programmed reduction (CO-TPR).It was found that the washcoat had strong vibration-shock resistance according to an ultrasonic test.The Pd-Ce0.4Zr0.6O2/substrate monolithic catalyst calcined at 400 ℃ showed 95% toluene conversion at a temperature as low as 210 ℃.Furthermore, the lowest temperature for 95% toluene conversion was increased by 40 ℃ after the catalyst calcined at 900 ℃, indicating that the catalyst had good thermal stability.The results revealed that the developed catalyst in this study was promising for eliminating volatile organic compounds (VOCs).
