UV Raman Spectroscopic Studies on Rapid Synthesis of AM-6 Zeolite and Formation Mechanism of -V-O-V- Atomic Wires

UV Raman Spectroscopic Studies on Rapid Synthesis of AM-6 Zeolite and Formation Mechanism of -V-O-V- Atomic WiresA 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 corner-sharing VO4 in the silicate gel plays an important role in the formation of -V-O-V- atomic wires in AM-6 crystals
