Synthesis and characterization of Zn and Co monocarboxy-phthalocyanines and investigation of their photocatalytic efficiency as TiO2 composites

We have synthesized and characterized A3B-type non-symmetrical metallophthalocyanines with monocarboxy group and three t-butylphenoxy groups. Respective TiO2-MPc composites were prepared. The composites were characterized by XRD, FTIR and DRS. TiO2-MPc composites were employed in the light-driven decomposition of 4-chlorophenol. All composites were active and almost total degradation was achieved.202
