TI  - Photocatalytic Inactivation of Salmonella typhimurium by Floating Carbon-Doped 
      TiO(2) Photocatalyst.

AB  - Photocatalysis application is considered as one of the most highly promising 
      techniques for the reduction in wastewater pollution. However, the majority of 
      highly efficient photocatalyst materials are obtained as fine powders, and this 
      causes a lot of photocatalyst handling and reusability issues. The concept of the 
      floating catalyst proposes the immobilization of a photocatalytic (nano)material 
      on relatively large floating substrates and is considered as an encouraging way 
      to overcome some of the most challenging photocatalysis issues. The purpose of 
      this study is to examine floating photocatalyst application for Salmonella 
      typhimurium bacteria inactivation in polluted water. More specifically, 
      high-density polyethylene (HDPE) beads were used as a photocatalyst support for 
      the immobilization of carbon-doped TiO(2) films forming floating photocatalyst 
      structures. Carbon-doped TiO(2) films in both amorphous and anatase forms were 
      deposited on HDPE beads using the low-temperature magnetron sputtering technique. 
      Bacteria inactivation, together with cycling experiments, revealed promising 
      results by decomposing more than 95% of Salmonella typhimurium bacteria in five 
      consecutive treatment cycles. Additionally, a thorough analysis of the deposited 
      carbon-doped TiO(2) film was performed including morphology, elemental 
      composition and mapping, structure, and depth profiling. The results demonstrate 
      that the proposed method is a suitable technique for the formation of 
      high-quality photocatalytic active films on thermal-sensitive substrates.
