Effect of Some Experimental Conditions of the Pulsed Plasma in Liquid on the Formation of Nanostructures

Optimal conditions for the synthesis of copper oxide nanoparticles under the pulsed plasma conditions carried out inside liquid media with different pH values and electrical conductivities were studied.To test the effect of liquid temperature on the composition of synthesized nanoparticles, syntheses were carried out at room temperature (20 0 ) and in a water bath at a temperature of 80 0 .A 5% aqueous solution of acetic acid (pH=2,41; =0,1123 S*l/*mol (20 0 ); =0,5673 S*l/*mol (80 0 )), distilled water (pH=7; =0,00009 S*l/*mol (20 0 ); =0,00011 S*l/*mol (80 0 )) and a 0.02% aqueous solution of sodium hydroxide (pH=11,7; =26,48 S*l/*mol (20 0 ); =156,154 S*l/*mol (80 0 )) were used.It was found that nanoparticles were synthesized in all samples, and the size and composition of the particles were greatly influenced by the electrical conductivity of the liquid and the composition of the liquid.
