| Abstract | 本发明公开了一种涂敷于磁性微型机器人的压电光催化剂的制备方法，通过溶胶‑凝胶法结合静电纺丝技术制备BaTiO3纳米纤维比例，并结合压电原子力显微技术表征铁/压电性和压电系数，将TiO2前驱体溶液涂敷到高压电系数的BaTiO3纳米纤维表面，经热处理后得到芯‑壳结构纳米纤维。BaTiO3/TiO2芯‑壳结构纳米纤维同时具有压电性能和光电效应，在超声振动和紫外光辐射条件下具有压电催化和光催化降解有机污染物的能力，在超声振动和紫外光辐射共同作用下，压电光催化协同效应能够显著提升催化降解效率。这种压电光催化剂可以涂敷于磁性微型机器人载体表面，实现催化降解过程的实时追踪与回收。 |
| Other Abstract | The invention discloses a preparation method of a piezoelectric photocatalyst coated on a magnetic micro-robot. The BaTiO3 nanofiber proportion is prepared by combining a sol-gel method with an electrostatic spinning technology, iron/piezoelectricity and a piezoelectric coefficient are represented by combining a piezoelectric atomic force microtechnique, a TiO2 precursor solution is coated to the surface of a BaTiO3 nanofiber with the high piezoelectric coefficient, and after heat treatment is carried out, a core-shell structure nanofiber is obtained. The BaTiO3/TiO2 core-shell structure nanofiber has piezoelectric property and photoelectric effect at the same time, and has the ability of piezoelectric catalysis and photocatalytic degradation of organic pollutants under the conditions of ultrasonic vibration and ultraviolet radiation, and under the combined action of ultrasonic vibration and ultraviolet radiation, the piezoelectric electro-photocatalytic synergistic effect can significantly improve the catalytic degradation efficiency. The piezoelectric photocatalyst can be coated on the surface of a magnetic micro-robot carrier to realize real-time tracking and recovery in the catalytic degradation process. |
