Abstract

The MXene-based transition metal oxide composite is a potential candidate for photocatalysts. Rod-like pseudohexagonal phase Nb2O5/Nb2CTx composites were synthesized by a simple hydrothermal oxidation of 2D layered Nb2CTx. The Nb2O5/Nb2CTx composites show superior photocatalytic activity for 98.5% of degradation of Rhodamine B (RhB) for 120 min and 91.2% of tetracycline hydrochloride (TC-HCl) for 180 min under visible light irradiation. The Schottky junction is formed between Nb2O5 nanorods and Nb2CTx and the photo-generated carriers are effectively separated, enhancing the photocatalytic activity of the Nb2O5/Nb2CTx. High photoactivity and cycle stability of Nb2O5/Nb2CTx composites indicate that hydrothermal oxidation of 2D layered Nb2CTx is an alternative to prepare efficient photocatalyst for degradation of organic pollutants.
