Abstract
A dielectric barrier discharge (DBD) plasma apparatus for synthesizing metal particles is provided. The DBD plasma apparatus includes an electrolyte vessel for receiving an electrolyte solution comprising metal ions; an electrode spaced-apart from the electrolyte vessel; a dielectric barrier interposed between the electrolyte vessel and the electrode such that, when the electrolyte solution is present in the electrolyte vessel, the dielectric barrier and an upper surface of the electrolyte solution are spaced-apart from each other and define a discharge area therebetween; and gas inlet and outlet ports in fluid communication with the discharge area such that supplying gas in the discharge area while applying an electrical potential difference between the electrode and the electrolyte solution cause a plasma to be produced onto the electrolyte solution, the plasma interacting with the metal ions and synthesizing metal particles. A method for synthesizing metal particles using a DBD plasma apparatus is also provided.
