Abstract
This paper demonstrates a sunlight-powered photocatalytic water filter using a TiO2 nanowires (TiO2NWs) and carbon nanotubes (CNTs) nanocomposite. The filter effectively removes microbial pathogens (bacteria and large viruses) through mechanical interception and photocatalytic generation of reactive oxygen species (ROS). The CNTs enhance the process by enabling pasteurization via visible light absorption and heating. A pilot study also showed promising results in reducing drug and pesticide traces.
