摘要：

A Pd-Y catalyst supported oil stainless steel wire mesh(Pd-Y/stainless steel wire mesh) for volatile organic compound(VOCs) combustion was prepared via anodic oxidation treatment. The activity tests for complete catalytic oxidation of toluene, acetone and ethyl acetate were investigated. The catalysts and stainless steel wire mesh support were characterized by means of scanning electron microscopy(SEM) and temperature programmed reduction(TPR) technologies. The results show that, after anodic oxidation procedure, a typical oxidized membrane can be, observed over stainless steel wire mesh,which is in favor of the dispersion efficiency for active species of Pd and Y. After 120 nun ultrasonic vibration test, there is no weight loss on the Pd-Y/stainless steel wire mesh sample. The total oxidation temperature for toluene, acetone, and ethyl acetate was at 220, 280, and 320 degrees C, respectively. Another exciting result is that the Pd-Y/stainless steel wire mesh catalyst shows stable activity for over 1000 h under the reaction of toluene oxidation at 240 degrees C.
