Dandelion-like micro-nano-hierarchical structure V2O5: Morphological evolution via surfactant-assisted hydrothermal synthesis and ultrafast adsorption of methylene blue under both acid and alkaline conditions

Key Points

• Methylene blue is rapidly adsorbed by V2O5 structures under varying pH conditions, indicating strong adsorption capacity.
• Notably, the adsorption process showed optimal results in both acid and alkaline environments.
• Hydrothermal synthesis with surfactants was employed to create unique micro-nano-hierarchical structures of V2O5, enabling increased surface area.
• The ability of these structures to efficiently remove dyes may have significant implications for pollution control and wastewater treatment.
