Figure 7From: Effects of architectures and H2O2 additions on the photocatalytic performance of hierarchical Cu2O nanostructures Photocatalytic activity of as-obtained Cu 2 O products with different amount of H 2 O 2 . Plots of concentration ratio of MO in an aqueous solution against given irradiation intervals in the presence of Cu2O products with different amount of H2O2: (a) 40 μL, (b) 100 μL, and (c) 1,000 μL.Back to article page
