AB  - The photocatalytic activity of sulphonated cobalt phthalocyanine immobilized onto 
      MCM-41 was investigated for decomposition of 2,4-dichlorophenol (2,4-DCP) in 
      aqueous solutions. Immobilization of anion sulpho-cobalt phthalocyanine to the 
      walls of MCM-41 was performed by pre-anchorage of 3-(aminopropyl)-triethoxysilane 
      (APTES) onto MCM-41 via post-synthesis method. X-ray diffraction, nitrogen 
      physisorption, diffuse reflectance spectroscopy, energy-dispersive X-ray and 
      FT-IR methods were used to characterize the product. Photocatalytic efficiency of 
      the prepared catalyst for degradation of 2,4-DCP was tested under illumination of 
      UV-A and visible light. The results obtained reveal that the photocatalyst is 
      very active in degradation of 2,4-DCP. The photodegradation process is completed 
      within 3h using a dose of 0.6g/L of the catalyst under UV irradiation. The 
      reactions follow a pseudo-first-order kinetics and the observed rate constant 
      values change with 2,4-DCP concentrations. The reproducibility of the catalyst 
      was tested. The reaction intermediates were identified by gas 
      chromatoghraphy-mass spectrometry (GC-MS) technique.
