| 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. |
