This article describes a visible-light-responsive photocatalyst of cobalt phthalocyanine (CoPc) and C-60 nanocomposites synthesized by a reprecipitation process. The full-spectrum-visible-light (420-800 nm) photocatalysis was demonstrated by mineralization under illumination of weak light intensity (in the order of 1 mW/cm(2)) for aqueous trimethylamine (TMA) and almost agreed with its absorption spectra. Other aqueous volatile molecules of acetaldehyde (AcH) and 2-mercaptoethanol (ME) were decomposed to CO2. CoPc/C-60 nanocomposite exhibited higher photocatalytic activity than independent nanoparticles of CoPc or C-60 as well as AlPc/C-60 composite. The oxidation power would arose from the hole generated at p/n junction like interface, which was suggested by photoelectrochemical oxidation experiments. The initial external quantum efficiencies of (EQE(h+)) estimated from CO2 generation reached to unity under the light intensity of 1 mW/cm(2), while later EQE(h+) was similar to 10(-4).
