Keywords:atmospheric-pressure plasma electrolysis, copper oxide nanoparticles, pH value

Recently, many researchers reported that atmospheric-pressure plasma electrolysis were possible to be applied to materials synthesis such as noble metals [1] and metallic oxide materials [2-4], due to its unique ability of producing highly reactive species. Previously, copper oxide (CuO or Cu₂O) nanoparticles have been synthesized successfully by plasma electrolysis. In this work, we investigated the effect of the pH of electrolyte on the products. The results showed that Cu₂O nanoparticles couldn’t be synthesized when the bulk solution was strong acidic.
