Hard Template Method

In this work, three-dimensional mesoporous MnO2, K/MnO2, Pt/MnO2 and K-Pt/MnO2 catalysts were prepared through hard-template method. The additional K/Pt had significantly improved the HCHO oxidation activity. The K-Pt/MnO2 catalyzed complete HCHO oxidation was achieved at 0℃ with space velocity (GHSV) at 50000 ml/(gand#183;h). With the excellent catalytic performance, K-Pt/MnO2 exhibited a higher ratio of Oads(surface adsorbed oxygen)/Olatt(surface lattice oxygen) and Mn3+/Mn4+ ions than the other catalysts. Meanwhile, it was still stable after running a 70h reaction. Overall, the K-Pt/MnO2 was a promising material for HCHO elimination.

Iron oxide supported on HY zeolite was prepared and exhibited excellent catalytic performance in the acylation of m-xylene with benzoyl chloride. It was characterized by XRD, BET, XPS, NH3-TPD and Py-IR. The catalytic activity of Fe2O3/HY is enhanced with the increase of Lewis acidic sites. Furthermore, the reaction parameters were optimized. Finally, the catalyst was easily separated reused for five runs without appreciable loss of catalytic activity.
