Continuous and Scalable Synthesis of Prussian Blue Analogues with Tunable Structure and Composition in Surfactant‐Free Microreactor for Stable Zinc‐Ion Storage

We represent a segmented flow surfactant-free microfluidic strategy for continuous synthesis of Prussian blue analogues (PBAs) with high dispersity and high crystallization. Representative zinc hexacyanoferrate (ZnHCF) nanocubes were successfully synthesized in a microfluidic reactor within a few minutes via the cooperation method and possessed lower contents of crystal water and Fe(CN)
