  • Method for preparing molybdenum oxide nanoparticles
    Patent number: 10479696
    Abstract: Provided is a method for preparing molybdenum oxide nanoparticles, including (a) preparing a precursor solution by dissolving a molybdenum salt in a first polar solvent, (b) generating an aerosol by applying ultrasonic waves to the precursor solution, and spraying the aerosol to a pre-heated reactor using a carrier gas, (c) obtaining molybdenum oxide micron-sized particles by pyrolyzing the aerosol, and (d) obtaining molybdenum oxide nanoparticles by dispersing the molybdenum oxide micron-sized particles in a second polar solvent and performing a solvothermal reduction reaction.
