Abstract
A method for preparing a platinum-loaded flower-like iron-cerium composite material includes: subjecting an iron salt solvent to thermal reaction and then calcining to obtain a flower-like porous iron oxide; in the presence of a chelating agent, reacting the flower-like iron oxide with a cerium salt in a solvent to obtain a flower-like iron-cerium composite material; mixing the flower-like iron-cerium composite material with a solution containing a platinum salt, the solvent is removed, and then performing low-temperature calcination to obtain a platinum-loaded flower-like iron-cerium composite material. The application of the platinum-loaded flower-like iron-cerium composite material includes: placing the platinum-loaded flower-like iron-cerium composite material into an environment containing toluene, performing heating at a low temperature, and completing treatment of the toluene. The present invention uses a fixed bed reactor to complete treatment of toluene, and preferably, the optimal temperature for low-temperature complete catalytic oxidation of toluene gas is 195° C.
