Abstract The photocatalytic performance of cobalt phthalocyanine (CoPc) immobilized onto MCM-41 was investigated for decomposition of methyl orange in aqueous solutions. The morphology and structure of the catalyst were analyzed by ultraviolet-visible spectroscopy(UV-vis), X-ray diffraction (XRD), Fourier transform infrared spectroscopy(FT-IR) and scanning electron microscopy (SEM). Photocatalytic efficiency of the prepared catalyst for degradation of methyl orange was tested under visible light irradiation. The photodegradation process was completed within 2 h using a dose of 0.04 g catalyst in the 0.05 g/L methyl orange solution under xenon lamp, and the removal rate reached 98.3%, even after four times' reuse, that number was 90%. The obtained results revealed that the photocatalyst was very active in degradation of methyl orange.
