Enhanced Photocatalytic Activity of TiO2 by (Tetracarboxyphthalocyaninatio) Cobalt (II)

Abstract:

Article Preview

(Tetracarboxyphthalocyaninato) cobalt (Ⅱ) was used as dye to enhance the photocatalytic activity of nano-TiO2 in visible light. The photocatalyzer was prepared by phthlocyanine Co and TiO2, which was called TPC. The photocatalytic process of removal of benzene was investigated in visible light and ultraviolet. Results reveal that TPC can enhance photocatalytic activity of TiO2. The Benzene removal of TPC catalyst at 4.5 h was 52.80 % in incandescent lamp, at the same time it was 41.86% higher than nano-TiO2. The Benzene removal of TPC catalyst at 4.5 h was 43.53% in fluorescent lamp, at then 28.03% higher than nano-TiO2. The Benzene removal of TPC catalyst at 4.5 h was 36.58% under ultraviolet, at then 5.50% lower than nano-TiO2. The Benzene removal of TPC catalyst at 4.5 h was 10.69% in incandescent lamp, at then 2.15% higher than nano-TiO2. TPC catalyst should enhance ability of liquid photocatalytic oxidation TiO2. The highest photocatalytic degradation of nitrobenzene and methylene blue were separately 76.60 % and 21.02 % under incandescent light.
