光转换介质和微流化学的集成为高效利用太阳能驱动化学反应提供了新的机会。最近,我们提出了一种具有独立光通道和反应通道的荧光流体光化学微反应器(FFPM)的设计,该设计在能量效率、灵活性和通用性方面显示出优异的优势。然而,微通道反应器的可扩展性的局限性仍然是一个有待克服的巨大挑战。在这里,我们通过3D打印技术通过2n编号策略说明了这种FFPM的可扩展性。通道形状、数量和通道间间距都得到了优化,蛇形FFPM显示出最佳的可扩展性,具有出色的转换率和巨大的吞吐量。具有多达八个通道的反应器已被制造,并显示在单通道反应器中获得的转化率相当,这为精细化学品的批量生产提供了一个可行的策略和优化的结构模型。
The integration of light-converting media and microflow chemistry renders new opportunities for high-efficient utilization of solar energy to drive chemical reactions. Recently, we proposed a design of fluorescent fluid photochemical microreactor (FFPM) with a separate light channel and reaction channel, which displays excellent advantages in energy efficiency, flexibility, and general use. However, the limitations of the scalability of the microchannel reactor are still a big challenge to be overcome. Herein, we illustrate the scalability of such an FFPM via a 2n numbering-up strategy by 3D printing technology. Channel shape, number, and interchannel spacing have been optimized, and the serpentine FFPM shows the best scalability with an excellent conversion rate and massive throughput. Reactors with up to eight channels have been fabricated and displayed conversions comparable to that obtained in a single-channel reactor, which provides a feasible strategy and an optimized structure model for batch production of fine chemicals.
