Abstract:

A novel 0.1% Pd-0.05% (mass fraction) Pt/stainless steel wire mesh catalyst was prepared for volatile organic compounds (VOCs) elimination. The catalyst was synthesized by stainless steel wire mesh as support and then treated by anodic oxidation technology to develop a porous membrane on the support. During the anodic oxidation process, various electrolytes were used to investigate the formation of porous membrane. And the catalytic performance of the catalysts was tested by using toluene and acetone combustion as model reaction. The temperatures of complete toluene and acetone conversion were decreased to 180 ℃ and 240 ℃, respectively. The morphologies of the stainless steel wire mesh supports and catalysts were characterized by means of scanning electron microscopy (SEM) and temperature-programmed reduction (TPR).
