Solar Light-Driven Photocatalytic Activity of CuO Nanospindles Synthesised Via Plasma-Liquid Interaction

This article introduces a simple single-step synthesis method of metal oxide nanoparticles using Plasma-Liquid Interaction (PLI). Due to the unique electrical, optical and catalytic properties of spindle shape copper oxide (CuO) nanoparticles, this article is focused on the synthesis of the same by generating plasma inside deionised water. SEM analysis of the nanoparticles shows the formation of spindle-shaped CuO nanoparticles arranged in flower-like structure. Photo-conductivity measurement of the CuO nanospindles indicates the generation of electron-hole pairs after illuminating light. Enhanced photocatalytic activity of the CuO nanospindles under simulated solar light is observed after adding H2O2 in Methylene Blue (MB) dye solution.
