Solid reagents, leaching catalysts, and heterogeneous photocatalysts are commonly employed in batch processes but are ill‐suited for continuous‐flow chemistry. Heterogeneous catalysts for thermal reactions are typically used in packed‐bed reactors, which cannot be penetrated by light and thus are not suitable for photocatalytic reactions involving solids. We demonstrate that serial micro‐batch reactors (SMBRs) allow for the continuous utilization of solid materials together with liquids and gases in flow. This technology was utilized to develop selective and efficient fluorination reactions using a modified graphitic carbon nitride heterogeneous catalyst instead of costly homogeneous metal polypyridyl complexes. The merger of this inexpensive, recyclable catalyst and the SMBR approach enables sustainable and scalable photocatalysis.

串联微间歇反应器中的连续多相光催化

批处理过程中通常使用固体试剂，浸出催化剂和非均相光催化剂，但不适用于连续流化学法。用于热反应的非均相催化剂通常用于填充床反应器中，该反应器不能被光穿透，因此不适用于涉及固体的光催化反应。我们证明了串联微间歇反应器（SMBR）可以连续利用固体材料以及流动中的液体和气体。该技术被用来开发选择性和有效的氟化反应，方法是使用改性的石墨碳氮化物非均相催化剂代替昂贵的均质金属聚吡啶基配合物。这种廉价，可回收的催化剂与SMBR方法的结合，可实现可持续且可扩展的光催化。
