Popis: International audience; Instant one-pot synthesis of functional layered double hydroxides (LDHs) is demonstrated for the first time using a continuous hydrothermal multi-step process. The as-prepared pristine material displays high crystallinity and very small LDH nanoparticle size, lateral dimensions below 100 nm and a thickness below 20 nm, all being achieved in only 5 s. This approach was extended to the preparation of i) pristine LDH with different compositions by varying the cation (Mg, Ni, or Zn) and the anion (CO3, NO3) and ii) functional LDH by varying the functionalization agent, for example long organic molecules (hybrid LDH), enzymes (bio-hybrid LDH) or inorganic metal/oxide nanocrystals (inorganic-LDH). Beyond the design of functional LDH, this paper presents proof of concept for a continuous, one-pot and multistep high temperature/high pressure (HT/HP) process for the assembly of nanoscaled materials.
