Overall, the flow synthesis method affords HT materials with a narrow distribution of properties. This, in turn, allows one to perform a systematic study of the effects of composition and synthesis conditions on the material properties of interest, opening the way to rational design of LDHs with targeted properties and scale up of their manufacture. For pore diameter 3.6 nm, r = 1.8 nm, R = 11.6 nm, which gives particle diameter 23.2 nm.
