摘要

以可溶性氨基酞菁3

3"'-四(二甲氨基)铜酞菁(α-TDMACuPc)为敏化剂

采用溶胶-凝胶法制备了氨基酞菁-二氧化钛(α-TDMACuPc-TiO2)光催化剂

通过紫外-可见吸收光谱(UV-Vis)、X射线衍射(XRD)对其进行了表征

并通过对甲基紫的光催化降解考察了α-TDMACuPc-TiO2光催化剂的催化性能。结果表明

α-TDMACuPc在近红外光区有较强的吸收

敏化后的二氧化钛吸收可被拓展至可见-近红外光区

而且二氧化钛呈金红石晶型。α-TDMACuPc敏化后的二氧化钛在可见-近红外光区的催化活性明显提高

在α-TDMACuPc质量分数为1%时催化活性达到最高

而且光催化剂具有较好的稳定性。

Abstract

An α-TDMACuPc-TiO2 photocatalyst was prepared through Sol-Gel method using 3

3"'-tetra-dimethylamino copper(Ⅱ) phthalocyanine (α-TDMACuPc) of a soluble amino phthalocyanine as a sensitizer. The photocatalyst was characterized by ultraviolet-visible spectroscopy (UV-Vis) and X-ray diffraction (XRD). Its photocatalytic performance for the degradation of methyl violet was evaluated. It showed that α-TDMACuPc sensitizer exhibited strong absorption in near-infrared region

and the absorption spectrum of sensitized TiO2 could be extended to visible near-infrared light region. Besides

the sensitized TiO2 features rutile structure. Its sensitization by α-TDMACuPc significantly improved the photocatalytic activity of TiO2 in visible near-infrared light region. The α-TDMACuPc-TiO2 photocatalyst with 1%(mass) α-TDMACuPc exhibited the highest catalytic activity as well as relatively good stability.
