微波辅助ZnFe-LDHs的合成及其异戊烯氧化脱氢性能的研究
Studies on microwave-assisted synthesis of ZnFe-LDHs and their performance in oxidative dehydrogenation of isopentene
摘要
Abstract
A series of ZnFe-LDHs were prepared via microwave-assisted co-precipitation method based on the structural properties of layered double hydroxides (LDHs) and the advantages of microwave-assisted synthesis and used for oxidative dehydrogenation of isopentene.The H2O/C5H10 molar ratio was lowered due to the easily hydroxylic surface.The results indicate that the microwave method can significantly shorten the synthesis time.ZnFe-LDHs with high crystallinity and purity were obtained at the microwave power of 600 W,microwave temperature of 95 ℃ and microwave time of 1 h.Compared with conventional method,the ZnFe-LDHs catalysts prepared with microwave method generated precursors exhibited higher activity and selectivity in oxidative dehydrogenation of isopentene.52％ yield of isoprene and 83％ selectivity were achieved when the H2O/CsH10 molar ratio was 5.7,which was greatly lowered.关键词
