F-doped hierarchical Nb2O5: Structural, optical and photocatalytic performance

A novel F-doped Nb2O5 with hierarchical structure (F-NbO) was designed to explore the photocatalytic activity. Compared to pure Nb2O5, F-NbO exhibits excellent characteristics in terms of light absorption ability, photogenerated charge separation efficiency, and surface O2 molecule adsorption. F-NbO was applied to dye wastewater treatment, which shows good photodegradation ability and catalytic stability. The related work has enriched the research scope of Nb2O5-based photocatalysts.
