Abstract:

High pure Mn-ZSM-5 zeolite was synthesized through one-step hydrothermal method by direct introduction of divalent manganese source under strong alkaline condition. The samples were characterized by XRD, FTIR, 29Si NMR, SEM, ICP and N2 adsorption-desorption techniques. The results indicated that manganese irons were incorporated into the zeolite skeleton. Using styrene oxidation as a probe reaction, H2O2 as the oxidant and Mn-ZSM-5 as the catalyst, the conversion of styrene reached 84.98%, turnover number was 208, styrene epoxide selectivity and yield was about 87.62% and 74.46%, respectively.The synthesized nano sized Mn-ZSM-5 is a promising catalyst for oxidation reactions.

Key words: Mn-ZSM-5 zeolite, Strong alkaline, Hydrothermal synthesis, Styrene oxidation
