摘要

利用太阳能分解四环素(TC)是一种处理废水的绿色策略。本文通过硬模板法和光沉积工艺,成功设计和合成了一种装饰有铂纳米粒子的异质中空结构二氧化钛,用于四环素的光降解。由于局部表面等离子体共振(LSPR)效应,负载在中空结构二氧化钛表面的铂纳米粒子可以增加可见光吸收。此外,由于 LSPR 激发的韧性电子振荡,铂纳米粒子表面的质子热空穴可以捕获 TiO2 的电子,由于铂和 TiO2 之间形成了肖特基结,从而有效地促进了光激发电荷载流子的分离。结合中空结构缩短电荷载流子传输路径和物理结构稳定性的天然优点,最优的铂/二氧化钛异质结杂化物在 300 W Xe 灯辐照下,30 分钟后的降解效率为 93.8%,速率常数为 0.09196 min-1,在 TC 光降解方面表现出优异的光催化活性和耐久性。这项工作展示了一种基于环保金属和半导体材料的异质混合催化剂,可用于包括但不限于三氯甲烷光降解等领域。

Enhanced light harvesting ability in hollow Pt/TiO2 nanoreactor for boosting tetracycline photodegradation

Utilizing solar energy to decompose tetracycline (TC) is a green strategy to treat wastewater. Herein, a heterogeneous hollow structured TiO2 decorated Pt nanoparticles were successfully designed and synthesized via hard-template approach and photo-deposition process toward TC photodegradation. The Pt nanoparticles loaded on the surface of hollow structured TiO2 can increase the visible light absorption due to the local surface plasmon resonance (LSPR) effect. Furthermore, owing to the tough electron oscillation of the LSPR excitation, the plasmonic hot holes on the surface of Pt nanoparticles can capture the electrons of TiO2, effectively facilitating the separation of photo-excited charge carriers because of the formation of Schottky junction constructed between Pt and TiO2. Combined the natural merits of shorten conveying path of charge carriers and physical structural stability for hollow structure, the optimal Pt/TiO2 hetero-junction hybrid showed superior photocatalytic activity and durability for TC photodegradation with the degradation efficiency of 93.8 ​% after 30 ​min and the rate constant of 0.09196 min−1 under 300 ​W Xe lamp irradiation. This work displays a heterogeneous hybrids catalyst based on eco-friendly metal and semiconductor materials which can be used in the fields including without limitation TC photodegradation.
