Template-Free Synthesis of Porous Cu2O Nanospheres at Room Temperature and Investigation on Their Adsorption Property
Figure 4
Adsorption curves of the aqueous solution of methyl orange (30 mg L−1, 200 mL) in the presence of Cu2O (0.05 g–0.12 g) at different intervals, where denotes the concentrations of MO changing following adsorption time and denotes the initial concentration of MO.
