摘要：

Dichloromethane (DCM) is one of the most commonly used solvents in industry. DCM easily accumulates and breaks down slowly; it is recognized as being carcinogenic. This research uses the sol-gel method to synthesize Mesoporous Mobil Catalytic Material Number 41 (MCM-41), Fe-MCM-41 and Pt-MCM-41 catalysts, and discusses the effectiveness of using these self-made catalysts to treat DCM. The qualities of each catalyst are identified using XRPD, BET, and SEM-EDS characteristic analyses. These results are then analyzed using the reaction kinetics theory. Results show that removal efficiency increases with the increase in temperature and concentration, and decreases with the increase in reaction chamber flow rates. Adsorption of DCM using mesoporous metal catalysts conforms to the Langmuir isotherm adsorption model. It was found that the best correlation results were observed for a Pt-MCM-41 catalyst.
