文摘

Phosphated TiO₂ photocatalysts with different phosphate content were synthesized by in situ phosphatation of sol-gel TiO₂. H₃PO₄ was used as a hydrolysis catalyst and as an anionic precursor. The solids were analyzed by several techniques to determine the structural, textural and optical characteristics. The photoactivity of the materials was tested in the degradation of 4-chlorophenol and 2,4-dichlorophenol, under UV irradiation.
