Abstract

Nb ₂O ₅ nanorods and nanospheres were synthesized, and their photocatalytic activity for methylene blue decomposition in water compared. Nb ₂O ₅ nanorods clearly displayed higher activity, despite their comparable surface area. With a shape-dependent surface acidity, hydrothermal stability, and high photoactivity, these Nb ₂O ₅ nanorods are a unique and exciting nanomaterial for non-classical photocatalytic mineralization of organic compounds in water.
