Solvothermal synthesis of metastable molybdenum, tungsten and vanadium oxides
It is shown that under the solvothermal conditions the polycondensation of molybdic, tungstic and vanadic oxoacids yields metastable oxide phases (h-MoO3, h-WO3, xerogel-V2O5 of lamellar structure) in the form of microcrystals 2–10 μm in size, while the hydrates of these oxides formed as the by-prod...
