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

Abstract:

(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.
