【摘要】：以微波辅助合成系列ZnFe-LDHs并用于异戊烯氧化脱氢,借助其表面易于羟基化的性质降低水烯比。结果表明,微波法可明显缩短合成时间,在微波功率为600W、微波温度为95℃和微波时间为1h的条件下可获得结晶度和纯度较高的ZnFe-LDHs。与传统法相比,以其为前驱体获得的催化剂在异戊烯氧化脱氢中表现出更高的活性和选择性,水烯比为5.7时,异戊二烯收率达到52%,选择性达83%,明显降低了水烯比。
[Abstract]:A series of ZnFe-LDHs was synthesized by microwave-assisted synthesis and used for oxidative dehydrogenation of isopentene. The results show that the synthesis time can be shortened obviously by microwave method. ZnFe-LDHs. with high crystallinity and purity can be obtained at microwave power of 600W, microwave temperature of 95 鈩，
