Vanadium oxide has been largely exploited as a catalyst in many industrial applications. In this article. we show the synthesis of vanadium oxide (V2O5): Nickel Oxide (NiO) composite using sol-gel method at optimum conditions. The composite nanomaterials were used to remove methyl orange from waste water via harnessing the photocatalytic activity of it which showed an excellent effici... https://www.johnperformance.com/product-category/brain-teaser-puzzles/
