摘要：

为获得可回收的高效降解有机污染物光催化剂,采用水热/溶剂热二步法在TiO₂纳米棒阵列上修饰Bi₂MoO₆纳米片,合成了Bi₂MoO₆/TiO₂复合纳米棒阵列可见光催化剂。对Bi₂MoO₆/TiO₂光催化剂的形貌、结构、化学元素组成和光学性能进行分析,并借助电化学工作站测试了Bi₂MoO₆/TiO₂纳米棒阵列异质结构的光电化学性能和光催化性能,分析了光催化活性增强的机制。结果表明:较窄带隙的Bi₂MoO₆修饰TiO₂纳米棒阵列拓宽了光谱响应范围,促进了光生载流子的有效分离和转移,显著提高了亚甲基蓝的光催化降解效率;TiO₂和Bi₂MoO₆之间形成type Ⅱ型异质结,Bi₂MoO₆/TiO₂的type Ⅱ型能带结构与可见光的扩展吸收之间的协同作用是光催化性能提升的内在机制。

Abstract:

In order to obtain a recyclable photocatalyst for efficient degradation of organic pollutants under visible light, TiO₂ nanorod arrays were modified with Bi₂MoO₆ nanosheets by hydrothermal solvothermal two-step method to obtain Bi₂MoO₆/TiO₂ composite. The morphology, structure, chemical element composition and optical properties of Bi₂MoO₆/TiO₂ photocatalyst were analyzed, and the photoelectrochemical and photocatalytic properties of Bi₂MoO₆/TiO₂ photocatalyst were tested with the help of electrochemical workstation in order to analyze the mechanism of enhanced photocatalytic activity. The results show that modification of TiO₂ nanorod arrays by Bi₂MoO₆ with narrow gap broadens the spectral response range, promotes the effective separation and transfer of photogenerated carriers, and obtains significantly enhanced photocatalytic degradation efficiency of methylene blue. The energy band structure diagram shows that type II heterojunction is formed between TiO₂ and Bi₂MoO₆, which promotes the separation and transfer of photogenerated electron holes. The synergistic effect between type II band structure of Bi₂MoO₆/TiO₂ and the extended absorption of visible light is the internal mechanism for the improvement of photocatalytic properties.

Key words: printing and dyeing wastewater treatment, photocatalytic biodegradation, photo-degradation mechanism, solvothermal method, visible light catalyst
