Synthesis and Spectral Characteristics for Zinc Tetraphenylporphyrin Modified Zinc Oxide Nanowires
A nest-like architectures (ZnO NAs) were prepared onto the conductive glass (ITO) by hydrothermal method.A metal-free porphyrin, tetraphenylporphyrin (H2TPP), was synthesized via Adler method.Zn ions with Zn-unsaturated coordination bonds on the surface of ZnO NAs were used as a template, and also H2 TPP was used as ”molecular fragments”.Zinc tetraphenylporphyrin (ZnTPP) molecules were obtained on the surface of ZnO NAs by in-situ method.ZnO NAs direct provides of zinc source makes ZnTPP stably coated on the surface of ZnO NAs nanosheet, formed a tight composite materials (ZnTPP/ZnO NAs).Due toZnTPP with four phenyls in meso position, the surface of ZnTPP/ZnO NAs was with hydrophobic property.In the photocatalytic experiment, the degradation selectivity for phenol (hydrophobicity) in the mixture of phenol and rhodamine B (hydrophily) was increased under visible irradiation.
