Synthesis and characterization of Pt/AgVO3 nanowires for degradation of atrazine using visible light irradiation

• Pt/β-AgVO3 nanowires were successfully prepared.
• By control weight percent of Pt photocatalytic activity can be controlled.
• Pt/β-AgVO3 can complete oxidation of atrazine under visible light irradiation.

A hydrothermal method was used to prepare β-AgVO3 nanowire, a photo-assisted deposition (PAD) method was used to prepare Pt/β-AgVO3 nanowires. β-AgVO3 and Pt/β-AgVO3 nanowires were characterized using XRD, BET, UV–Vis spectroscopy, Pl, TEM, and XPS techniques. The results reveal that platinum was present as platinum metal and it is well dispersed on the surface of β-AgVO3 nanowire. The photocatalytic degradation of atrazine under visible light irradiation was used to measure the photocatalytic performance of the β-AgVO3 and Pt/β-AgVO3 nanowires. The photocatalytic activity of Pt/β-AgVO3 nanowires have higher photocatalytic activity than β-AgVO3 nanowire. The reason for the high photocatalytic activity of Pt/β-AgVO3 nanowires may be due to the synergic effect between Pt and β-AgVO3.
