Catalytic decomposition of 1,2-dichlorobenzene using Pt-loaded nanoporous zeolite MFI catalyst.
Nanoporous zeolite MFI was prepared by using HClO4 as a promoter. A significant proportion of the synthesized zeolite MFI nanoparticles exhibited nanoporous characteristics. Although the synthesis of the zeolite MFI was completed within 6 h, the crystallinity of all the zeolite MFI was shown to be high. The synthesis time of approximately 6 h used in this study was much shorter than the conventional hydrothermal method. The feasibility of the new nanoporous zeolite MFI towards the gas phase catalytic oxidation of a model for dioxin, 1,2-dichlorobenzene, was tested by comparing the catalytic activity of Pt/nanoporous zeolite MFI with that of a Pt/gamma-Al2O3 catalyst. The catalytic activity of the Pt/nanoporous zeolite MFI was higher than that of the Pt/gamma-Al2O3 catalyst. The internal surface area and acidity appears to be a major factor for the decomposition of 1,2-dichlorobenzene.
