    • Abstract

       

      In this paper, interaction of the air plasma generated in an atmospheric pressure pin-to-solution electrical discharge with aqueous solutions of silver nitrate, copper nitrate and also their mixture is experimentally investigated inthe cathode-plasma electrolysis configuration. Experiments show that a black (green–blue) powder is obtained for pure solution of AgNO$_3$(Cu(NO$_3$)$_2$ ·3H$_2$O). Through X-ray diffraction (XRD) characterizations, the black (green–blue) powder is found to be Ag$_2$O$_2$(Cu$_2$(OH)$_3$NO$_3$). On the other hand, the electrolysis product for AgNO$_3$/Cu(NO$_3$)$_2$ · 3H$_2$O mixture solution is a black–brown powder. XRD and EDS analyses of the powder along with its FESEM images reveal that it is truly Cu$_2$(OH)$_3$NO$_3$ micro-plates covered sparsely with Ag$_7$NO$_{11}$ nanoparticles of diameter $\sim$30 nm.
