Abstract

Iron(III) phthalocyanine modified titanium dioxide, FeIIIPc/TiO2, photocatalyst was prepared. The photocatalyst reveals enhanced activity for the degradation of organic pollutants as compared to nonmodified TiO2. The photodegradation of p-aminobenzoic acid (1), p-nitrobenzoic acid (2), p-chlorophenoxyacetic acid (3), salicylic acid (4), and aniline (5) was found to be significantly enhanced in the presence of the FeIIIPc/TiO2 photocatalyst as compared with the nonmodified TiO2 photocatalyst. The enhanced activity of FeIIIPc/TiO2 is attributed to the cooperative functions of the two components of the photocatalyst, Iron(III) phthalocyanine and the TiO2 semiconductor in the generation of OH radicals.
