The following phases were prepared: an α phase Li1.4(VO)1.3[H2V10O28]· nH2O and a β phase Li0.6 – xH1.4 + x[V12O31 – y/2] · nH2O (0 ≤ x ≤ 0.5, 1.3 ≤ y ≤ 2.0) with a layered structure. Li0.4V2O5 · H2O nanorods with the interlayer distance 10.30 ± 0.08 Å were synthesized at 180°C in an autoclave. The morphology, IR spectra, and main formation processes for these polyvanadates were studied Полный текст |
