The V₂O₅ nano-particles were synthesized by using the Liquid Phase Precursor (LPP) method in air atmosphere. LPP method is a new synthesis technology conducted by using the nano-structured cellulose (pulp) and vanadyl sulfate hydrate (VO[SO₄]₇H₂O) solution, that is called the precursor. A vanadium solution was impregnated into the pulp for trapping vanadium ions. Impregnated pulp was fired at 400 to 600°C to evaporate the cellulose and then V₂O₅ particles were obtained.
Burning temperatures and decomposition behavior of impregnated pulp as a function of precursor concentration were measured by TG–DTA. Their crystal structure and morphology of obtained particles were evaluated by XRD, FE-SEM and TEM. Nano-sized V₂O₅ particles of around 70 nm were obtained without grinding by firing at 400°C for 1 h. Burn-out mechanism of impregnated pulp was studied.
