Накратко на български

Микромотори, задвижвани от светлина, се разработват за автоматично пречистване на замърсена вода чрез разграждане на органични отпадъци. Тези частици се движат активно във течността, което подобрява контакта с замърсителите и помага за осигуряването на чиста вода.

Versatile Micromotors for Photocatalytic Environmental Remediation

Environmental pollution, especially water pollution, is causing significant deleterious effects on marine life and even human health. Access to clean water has always been the most basic desire of many people in developing countries. Herein, this “Versatile Micromotors for Photocatalytic Environmental Remediation” project designs and fabricates novel self-propulsion micromotors, which can transform the chemical fuels into kinetic energy and then automatically “fly” in the fluid, to remove the polluting substances in the contaminated water in an efficient and controlled manner. The adoption of nano/micromotors for environmental remediation is a cutting-edge concept, which also contains multidiscipline knowledge and skills. These tiny intelligent “on-the-fly” micromotors can transform energy from their environment to autonomous movement and therefore usually exhibit a more efficient degradation of organic pollutants as compared to the stationary ones because of the enhanced mixing and mass transfer and effective contact probability in the water by vigorous movement. Hence, this project offers an efficient and intelligent method to address the global environmental degradation challenge, which finally contributes to Sustainable Development Goal 6: Clean Water and Sanitation. Objectives of this Marie Skłodowska Curie Action (MSCA) have been to (i) develop novel photocatalytic micromotors to clean polluted water bodies under the illumination of visible light, (ii) establish the composition-microstructure-performance-application relationship of photocatalytic micromotors via advanced characterization and analysis techniques, and (iii) understand the effect of size and structure on the movement behavior of micromotors via visualized path tracking method. A parallel objective of the MSCA Individual Fellowship is to foster the career development of the individual researcher.

Цел на проекта

Environmental degradation issue is a global concern. Great efforts have been made to develop efficient and green approaches for wastewater treatment. Self-propelled nano/microrobots are the forefront of nanotechnology, holding great promise for environmental remediation. Visible light driven semiconductor photocatalyst would be the great catalyst to power such micromachines for environmental remediation. BiVO4 has attracted researchers’ great interest. However, its drawbacks such as significant recombination of photogenerated electron–hole pairs, poor electrical conductivity and slow hole transfer kinetics limit its applications. To enhance the photocatalytic efficiency, this project elaborately develops light-responsive tubular micromotors with smart material design strategy: BiVO4 is robust visible light absorber; ZnO nanorod arrays act as electron transfer channel; rGO films function as electron acceptor; and Co-Pi serves as hole acceptor and catalytic site. The Microbots4Enviro project aims to: (i) establish novel tubular Co-Pi/BiVO4/ZnO/rGO micromotors; (ii) study the comprehensive performance of micromotors in the polluted water with three types of contaminant models (i.e. dye, explosive and bacteria model); and (iii) integrate abundant micromotors in 3DP-motor and demonstrate the pilot-scale test in artificial 5×5m2 pool for environmental remediation. This project will bring an experienced researcher, Dr. Huaijuan Zhou to undertake this cutting-edge multidisciplinary research project at UCT Prague in Czech Republic under the supervision of Prof. Martin Pumera, Director of Center for Advanced Functional Nanorobots. This fellowship will not only restart her research career, but also broaden her knowledge and expertise in the emerging area of self-propelled autonomous nano/micromachines. This project contributes to creating a strong scientific and technical base for European science and technology, and fostering the competitiveness and growth of EU economy.
