摘要
Tantalum nitride (Ta3N5) photocatalyst was synthesized by ammonization of the water-soluble tantalum oxalate precursors. The monolithic Ta3N5 nanoparticles with the average size of 40 nm were prepared at 800 degrees C in the flowing ammonia. Various analytic techniques had been applied to characterize the phase transformation, microstructure, optical absorption and photocatalytic activity of the well-crystallized Ta3N5 particles. The as-prepared Ta3N5 nanoparticles exhibited higher photocatalytic activity for the degradation of methylene blue and rhodamine B under visible light irradiation than bulk Ta3N5 particles. This work provides a new approach to design and fabricate Ta3N5 nanostructure, the promising candidate for visible-light photocatalyst.
