Thus, analyzing the available literature on the flow syntheses of LDHs by co-precipitation we note that plate-like particles with the aggregate sizes in the range of 20-50 nm could be obtained, compared to large 3D particles typically synthesized in batch. Furthermore, although narrow particle size distribution could be attained in micro-reactors, we show that it is sufficient to reduce the size to a mm-scale reactor, easier for scaling, but to carefully select the conditions such that mixing time is in the order of the micromixing characteristic time. This results in the narrow distribution of not only particle sizes, but also the key morphological properties of the obtained materials.
