In this study, WO₃ nanorods have been fabricated by simple anodization in the presence of different amounts of citric acid and at different anodization times. A comprehensive morphological, structural, electrochemical and photoelectrochemical characterization of different samples has been carried out. Moreover, a formation mechanism for WO₃ nanorods has been proposed. Finally, these nanostructures have been proven to be excellent visible-light photoelectrocatalysts to remove persistent organic pollutants present in wastewaters, such as fenamiphos. Almost the 80% of this molecule was eliminated from the test solution after 180 min of irradiation, indicating the great potential of these WO₃ nanorods, fabricated following a very simple and unexpensive procedure, in the energy and environmental fields as photoelectrocatalysts.

在这项研究中，WO ₃纳米棒已通过简单的阳极氧化在不同量的柠檬酸和不同的阳极氧化时间下制造。对不同样品进行了全面的形态、结构、电化学和光电化学表征。此外，还提出了WO ₃纳米棒的形成机制。最后，这些纳米结构已被证明是出色的可见光光电催化剂，可用于去除废水中存在的持久性有机污染物，如苯胺磷。在照射 180 分钟后，几乎 80% 的这种分子从测试溶液中消除，表明这些 WO ₃的巨大潜力 纳米棒，按照非常简单和廉价的程序制造，在能源和环境领域作为光电催化剂。
