AB  - An enhanced ferromagnetic property, visible light active TiO(2) photocatalyst was 
      successfully synthesized by supporting strontium ferrite (SrFe(12)O(19)) onto 
      TiO(2) doped with nitrogen (N) and compared with N-doped TiO(2). The synthesized 
      catalysts were further characterized with X-ray diffraction (XRD), transmission 
      electron microscope (TEM), energy dispersive X-ray spectroscopy (EDS), BET 
      surface area analysis, vibrating sample magnetometer (VSM), X-ray photon 
      spectroscopy (XPS) and visible light spectroscopy analysis for their respective 
      properties. The XRD and EDS revealed the structural and inorganic composition of 
      N-TiO(2) supported on SrFe(12)O(19). The supported N-TiO(2) exhibited a strong 
      ferromagnetic property with tremendous stability against magnetic property 
      losses. It also resulted in reduced band gap (2.8 eV) and better visible light 
      absorption between 400 and 800 nm compared to N-doped TiO(2). The photocatalytic 
      activity was investigated with a recalcitrant phenolic compound namely 
      2,4-dichlorophenol (2,4-DCP) as a model pollutant under direct bright and diffuse 
      sunlight exposure. A complete degradation of 2,4-DCP was achieved with an initial 
      concentration of 50mg/L for both photocatalysts in 180 min and 270 min 
      respectively under bright sunlight. Similarly the diffuse sunlight study resulted 
      in complete degradation for supported N-TiO(2) and >85% degradation N-TiO(2), 
      respectively. Finally the supported photocatalyst was separated under permanent 
      magnetic field with a mass recovery  approximately  98% for further reuse.
