流动光化学微反应器中多级结构功能界面的构建及性能研究

流动光化学微反应器因其内部均匀的光辐射以及高传质传热效率而受到人们的广泛关注。在这类反应器中，通道界面作为流体流动和光能输入的主要场所，其结构和表面性质是影响光传递和物质输运的核心因素。通过微观结构的设计实现物质扩散和光能传输在界面处的协同调控，是提高光催化反应过程整体效率的有效途径。本项目将胶体与界面化学、流体力学与光化学反应过程相结合，以数值仿真方法为理论指导，以高精度激光加工技术为桥梁，将光子晶体与有序微结构阵列相结合，来设计同时具有高效光能利用和高效物质传输的多级结构功能界面。项目的设立和开展，一方面能够得到简单有效构建多级有序结构界面的普适性方法；另一方面，也将有利于对多级结构界面发生的光传递过程、流体流动情况和光催化反应过程等重要的基础性问题进行研究，获得更深层次的认识，为发展高性能流动光化学微反应器提供有益信息。

Flow photochemical microreactors have attracted widespread attention due to their uniform light radiation and high mass and heat transfer efficiency. In this type of reactor, the channel interface is the main site for fluid flow and light energy input, its structure and surface properties are the core factors that affect light transfer and material transport. The coordinated regulation of material diffusion and light energy transmission at the interface through the design of the interface structure is an effective way to improve the overall efficiency of the photocatalytic process. This project combines colloids and interface chemistry, fluid mechanics, and photochemistry, uses numerical simulation methods as theoretical guidance, and uses high-precision laser processing technology as a bridge, combine photonic crystals and the ordered microstructure arrays to design a multi-scale structure function interface with efficient light energy utilization and efficient material transport. The establishment and development of this project, on the one hand, can obtain a universal method for simple and effective construction of multi-scale ordered structural interfaces; on the other hand, it will also be beneficial to the research on the fundamental issues of light transfer, fluid flow and photocatalysis process that occurred simultaneously at the multi-scale structural interfaces. This project will give us much deeper understanding of the regulatory role of the interface structure, and also provide useful information for the development of high-performance flow photochemical microreactors.
