A new class of supported photocatalysts is introduced with high activity under UV irradiation for the removal of dye contaminations. The composition comprises silicoaluminates (zeolite Na–Y) as the support, TiO2 or Ti derivatives as the semiconductor, metal ion or metallocomplexes as the promoter of reaction or photosensitizer was used for the photocatalytic performance. The efficiency of catalysts was determined based on the amount of degradation of dye contamination. The effect of several parameters was investigated in the removal of dye. Mineralization of wastewater was obtained by using COD analysis. All of catalysts showed a good efficiency in the removal and degradation of pollution.
