Anticorrosion Coated Stainless Steel as Durable Support for C-N-TiO<sub>2</sub> Photo Catalyst Layer
The development of durable photocatalytic supports resistant in harsh environment has become challenging in advanced oxidation processes (AOPs) focusing on water and wastewater remediation. In this study, stainless steel (SS), SS/Ti (N,O) and SS/Cr-N/Cr (N,O) anticorrosion layers on SS meshes were d...

| description | The development of durable photocatalytic supports resistant in harsh environment has become challenging in advanced oxidation processes (AOPs) focusing on water and wastewater remediation. In this study, stainless steel (SS), SS/Ti (N,O) and SS/Cr-N/Cr (N,O) anticorrosion layers on SS meshes were dip-coated with sol gel synthesised C-N-TiO<sub>2</sub> photo catalysts pyrolysed at 350 °C for 105 min, using a heating rate of 50 °C/min under N<sub>2</sub> gas. The supported C-N-TiO<sub>2</sub> films were characterised by scanning electron microscopy (SEM) coupled with energy dispersive spectroscopy (EDS), X-ray diffraction (XRD) and Raman spectroscopy. The results showed that C-N-TiO<sub>2</sub> was successfully deposited on anticorrosion coated SS supports and had different morphologies. The amorphous C and TiO<sub>2</sub> were predominant in C-N-TiO<sub>2</sub> over anatase and rutile phases on the surface of SS and anticorrosion supports. The C-N-TiO<sub>2</sub> coated films showed enhanced photocatalytic activity for the decolouration of O.II dye under both solar and UV radiations. The fabricated C-N-TiO<sub>2</sub> films showed significant antibacterial activities in the dark as well as in visible light. Herein, we demonstrate that SS/Ti(N,O) and SS/Cr-N/Cr(N,O) anticorrosion coatings are adequate photocatalytic and corrosion resistant supports. The C-N-TiO<sub>2</sub> photo catalytic coatings can be used for water and wastewater decontamination of pollutants and microbes. |
