UV Raman Spectroscopic Studies on Rapid Synthesis of AM-6 Zeolite and Formation Mechanism of —V O V— Atomic Wires
摘要
Abstract
A rapid synthesis(4 h) method of AM-6 zeolite was reported. The effects of the n(K+ )/n(V4+) ratio and the pH value of the initial gel on the purity and crystallinity of AM-6 zeolite were investigated. The synthesis conditions optimize at n ( K + )/n ( V4+ ) = 3 and pH = 12.5. The formation mechanism of the V—O—V— atomic wires in AM-6 was monitored by UV Raman spectroscopy in combination with UV-Vis spectroscopy and X-ray diffraction patterns. It turns out that the formation of the VO3- chains composed of cornet-sharing VO4 in the silicate gel plays an important role in the formation of—V—O—V— atomic wires in AM-6 crystals.关键词
