摘要: We demonstrate operation of an aqueous electrochemical cell with atmospheric-pressure microplasma cathode and a solid metal anode for the rapid production colloidal nanoparticles. Microplasmas are miniaturized versions low-pressure glow discharges that operate nonthermally at high pressures (∼1atm) contain energetic electrons. Aqueous cations directly reduced by electrons in without presence or chemical reducing agents. Kinetic studies performed UV-visible absorbance spectroscopy suggest particle nucleation growth coupled to redox reactions initiated through plasma-liquid interactions.
