Abstract：
Nb2O5 nanorods were fabricated by acetic acid solvothermal route combined with heat treatment of as-obtained one dimensional (1D) niobium oxide nanowires at 400°C for 1h. XRD, SEM, TEM analyses indicate that Nb2O5 nanorods prepared by calcination have hexagonal phase and crystalize along [001] direction. These Nb2O5 nanorods can be used as catalysis for the degradation of methylene blue (MB) and rhodamine B (RhB) aqueous solution under UV light illumination. Experimental results show that Nb2O5 nanorods possess well photocatalytic activity for the degradation of both MB and RhB under UV light, which is of great interest in environmental purification. Photocatalytic efficiency decreases with the increase of dye concentration, and the removal effect of MB is better than that of RhB due to strong adsorption of MB onto Nb2O5 nanorods.
