近年来，随着电子设备朝着微型化、高能耗方向发展，微型供能系统以其高效和环境友好等特点被广泛研究，作为微型燃料能源系统的重要能源载体之一，氢源问题成为了限制其发展的瓶颈之一。微流控光催化重整制氢不但偶联了太阳能和生物质两种可再生资源，更可实现在微型芯片上即时产氢，避免了微型燃料电池需额另外储氢的难题和安全隐患。生物质醇光催化重整制氢反应效率的提高很大程度上受到反应工艺的限制。. 本项目将采用生物醇水溶液液滴用改性光催化剂乳化的方法，使制氢反应在微乳液界面上进行，每个液滴都可作为独立的微反应单元。通过控制液滴在多相体系的流动等，使微液滴各处反应在均匀光照下进行，实现连续流动高效制氢。这种方法不但可以提高光利用率、催化剂和原料的使用效率实现节能省料，还可源源不断高效产氢。本项目将进行微通道芯片的设计制备，重点研究光催化剂颗粒在微液滴界面的乳化催化过程，探索液滴微流控光催化剂制氢机理，构建新型微流控制氢反应体系。

As electronic devices develop toward miniaturization in recent years, extensive researches have been carried out for micro fuel supply system for its high efficient and environment friendly features. However, hydrogen source problem limits its development. Hydrogen production from microfluidic photocatalytic reforming method, not only couples solar energy and renewable biomass resources, but also achieves instant hydrogen production on a microchip. This method could avoid hydrogen storage and carrying problems of micro fuel cell.. The improvement for hydrogen production efficiency of bio-alcohol catalytic photo-reforming is strictly limited by the reaction process. This project will use bio-alcohol and water mixture droplets overwrapped by modified photocatalysts to produce hydrogen, the reaction for each drop occurs at the interface, for which each droplet can be considered as an independent micro-reactor. Continuously flow and high-efficiency hydrogen production could be achieved by controlling the droplet flow in multiphase under uniformly illumination. This method could not only improve the utilization efficiency of light, catalyst and raw materials to achieve energy and materials saving, but also obtain a steady stream of hydrogen. The project involves in designing and preparing micro-channel chips, and mainly focuses on the study of photocatalyst particle on the micro-droplet interface for emulsion and catalysis process. We will try to explore the mechanisms of microfluidics photocatalyst hydrogen production. An innovating microfluidic hydrogen production reaction system will be constructed.
