摘要：

Rose-like crystalline particles of ammonium vanadium sulfate hydroxide (NH4V3(OH)(6)(SO4)(2)) were synthesized by a solvothermal route using dimethyl sulfoxide (DMSO)-water as the solvent. Following a thermal decomposition process, rose-like V2O5 micro-architectures were fabricated via the in situ generated single-crystalline nanoparticles. When used as the cathode material in lithium-ion batteries, the rose-like V2O5 micro-architecture exhibited high initial discharge capacity. Sphere-like precursor was also prepared via selecting suitable carboxylic acid. This facile synthesis method would be used to prepare various vanadium oxides with different morphologies as well as other compounds. (c) 2008 Elsevier Masson SAS. All rights reserved.
