Micro-Batch flow reactor for the photoproduction of H2O2 from water/real seawater

Abstract

Photocatalytic generation of H₂O₂ with heterogeneous catalysts has attracted much attentions and impressive strategies have been used to increase the photocatalytic efficiency. However, applications of these strategies to large scale are still underdeveloped. For this reason, development of flow photocatalytic strategy is highly necessary. Considering this, we have developed a serial micro-batch flow reactor for the generation of H₂O₂ which could easily scale up the reaction to1L scale with high reproducibility with the modified g-C₃N₄. With this flow reactor, the generated concentration of H₂O₂ has been reached to 6.89 mM and 5.89 mM in pure water and seawater, respectively.
