一步水热合成Mn-ZSM-5纳米分子筛及其性能
Synthesis and Property of Nano-sized Mn-ZSM-5 Zeolite via One-step Hydrothermal Method
摘要
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, H202 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.关键词
