Abstract

Abstract Four interrelated issues have been arising with the development of modern industry, namely environmental pollution, the energy crisis, the greenhouse effect and the global food crisis. Photocatalysis is one of the most promising methods to solve them in the future. To promote high photocatalytic reaction efficiency and utilize solar energy to its fullest, a well-designed photoreactor is vital. Photocatalytic optofluidic microreactors, a promising technology that brings the merits of microfluidics to photocatalysis, offer the advantages of a large surface-to-volume ratio, a short molecular diffusion length and high reaction efficiency, providing a potential method for mitigating the aforementioned crises in the future. Although various photocatalytic optofluidic microreactors have been reported, a comprehensive review of microreactors applied to these four fields is still lacking. In this paper, we review the typical design and development of photocatalytic microreactors in the fields of water purification, water splitting, CO2 fixation and coenzyme regeneration in the past few years. As the most promising tool for solar energy utilization, we believe that the increasing innovation of photocatalytic optofluidic microreactors will drive rapid development of related fields in the future.
光催化微流控反应器研究进展
摘要随着现代工业的发展,出现了四个相互关联的问题,即环境污染、能源危机、温室效应和全球粮食危机。光催化是未来解决这些问题最有前途的方法之一。为了提高光催化反应效率并充分利用太阳能,设计良好的光反应器至关重要。光催化光流体微反应器是一种很有前途的技术,它将微流体的优点带到了光催化中,具有表体积比大、分子扩散长度短和反应效率高的优点,为未来缓解上述危机提供了一种潜在的方法。尽管已经报道了各种光催化光流体微反应器,但对应用于这四个领域的微反应器仍缺乏全面的综述。本文综述了近几年来光催化微反应器在水净化、水分解、CO2固定和辅酶再生等领域的典型设计和发展。作为最有前景的太阳能利用工具,我们相信光催化光流微反应器的不断创新将推动未来相关领域的快速发展。
