A novel inorganic precipitation-peptization method for VO2 sol and VO2 nanoparticles preparation: Synthesis, characterization and mechanism

A simple inorganic precipitation-peptization method was proposed to prepare VO2 sol in air under room temperature using VOSO4 as a vanadium source, NH3⋅H2O as a precipitating agent, and H2O2 as an initiating agent. VO2 nanoparticles were prepared by annealing the VO2 xerogel.125
