Embodiment 1

[0023] A preparation method of a self-driven micro-nano motor using pine pollen as a template comprises the following steps:

[0024] (1) Potassium permanganate solution preparation: Mix appropriate amount of potassium permanganate and pure water and stir evenly to obtain potassium permanganate solution;

[0025] (2) Treatment of pine pollen: soak pine pollen in oleic acid;

[0026] (3) Preparation of self-driven micro-nano motor: Add the potassium permanganate solution obtained in step (1) to step (2), stir slowly, then wash and vacuum-dry to obtain a self-driven micro-nano motor with pine pollen as a template. Namada.

[0027] Performance Characterization:

[0028] figure 1 The FESEM image of the self-propelled micro-nanomotor using pine pollen as a template. It can be seen from the figure that pine pollen is an ellipsoid particle with a diameter of 50 μm, which is divided into two parts: the body and the air sac. Porous structure, the thickened part of the outer wall o...

Abstract

The invention discloses a self-driven micro-nano motor taking pine pollen as a template, and a preparation method thereof. Potassium permanganate and oleic acid are used as raw materials, pine pollenis used as the template, a potassium permanganate solution is added into pine pollen soaked with oleic acid, potassium permanganate and oleic acid are subjected to a redox reaction to generate manganese dioxide nanoparticles, and the manganese dioxide nanoparticles are loaded on the pine pollen to prepare the self-driven micro-nano motor with the pine pollen as the template. The self-driven micro-nano motor has the advantages of large specific surface area, large pore volume and good adsorption performance, reduces the recycling difficulty of a catalyst material, has the functions of carrying,conveying and releasing, and can effectively adsorb and degrade organic pollutants in water to achieve wastewater treatment and purification.

Description

technical field [0001] The invention belongs to the technical field of micro-nano motors, and in particular relates to a self-driven micro-nano motor using pine pollen as a template and a preparation method thereof. Background technique [0002] Micro-nano motors refer to devices that are at the nanometer or micrometer level, can move through different principles, have special functions or can perform microscopic system tasks. Due to the advantages of small size, light weight and strong driving force, it has shown outstanding advantages in sensing detection, micro-nano processing and environmental governance, especially in the field of biomedicine, which has great application prospects. In recent years, micro-nano motors have developed rapidly, and their preparation methods and application fields have made great progress. At present, micro-nano motors powered by chemical energy, such as catalytic nanowires, double-sided spherical micro-nano motors, and multi-layer tubular m...
