PREPARATION METHOD OF ZNO NANO-RODS USING A PLASMA JET AND PHOTO-CATALYTIC PROPERTY OF ZNO NANO-RODS

摘要

PURPOSE: A preparing method of a zinc oxide nano rod using a plasma jet, and a photocatalytic activation of the zinc oxide nano rod using thereof are provided to simply prepare nano sized zinc oxide using the plasma jet. CONSTITUTION: A preparing method of a zinc oxide nano rod comprises the following: generating a thermal plasma jet in the inside of a thermal plasma reactor using a direct current discharge; melting and vaporizing zinc particles after inserting the zinc particles into the thermal plasma jet; and inserting oxygen as reaction gas into the thermal plasma jet to react the vaporized zinc particles with the oxygen, and cooling the reacted vaporized zinc particles and the oxygen to synthesize the zinc oxide nanorod. Gas for generating the thermal plasma jet is argon gas.
