Additive effect of nano-size platinum to pretreated iron based catalyst on complete oxidation of toluene

Catalytic oxidation of toluene (VOC) was carried out to assess the properties and catalytic activities of iron oxide catalyst promoted with nano size platinum. The properties of the prepared catalysts were characterized by the Brunauer Emmett Teller (BET) surface area method and by conducting Temperature programmed reduction (TPR), X-ray diffraction (XRD), and Tansmission electron microscopy (TEM) analyses. The experimental results showed that the addition of platinum to spent iron based catalyst shifted its conversion curve for the total oxidation of toluene to lower temperature. It was also observed that the increase in toluene conversion due to the addition of nano-size platinum was highly dependent on the surface oxygen mobility of the catalyst.
