- Abstract
In this study, one-dimensional AgVO nanowires were prepared by a facile hydrothermal process and developed as a novel visible-light-sensitive photocatalyst. AgVO nanowires were single-crystalline with large specific surface area and good visible-light absorption performance. The degradation of bisphenol A (BPA) by AgVO was systematically investigated under visible-light irradiation, and the influence parameters were studied. Experimental results indicated that AgVO nanowires had excellent photocatalytic activities and the degradation efficiency of BPA could reach 100 % within 150 min with 1 mg/mL AgVO. Intermediates of the degradation reaction were detected by high performance liquid chromatography coupled with mass spectrometry, and a possible degradation pathway was proposed. In addition, after eight cycles for the photodegradation of BPA, AgVO did not exhibit significant loss of photocatalytic activity, confirming its stability and long-time reusability. The photocatalytic mechanism was studied by active species trapping experiments, revealing that the holes (h) and hydroxyl radicals ( $${\cdot}{\text{OH}}$$ ) played key roles in RhB degradation. This study provides a potential effective AgVO nanowire photocatalyst for water purification and other applications.
