(129h) High Yield Stoichiometric Synthesis of ZIF-8 Nanoparticles Using Novel Reactor
In this work, a scalable, solution phase synthesis is demonstrated for ZIF-8 nanoparticles with uniform diameters in the range of 40-80 nm. ZIF-8 is synthesized with 89% yield using stoichiometric precursor concentrations using a novel reactor. Turbulence created by the reactor provides homogeneous conditions in the reaction volume resulting in improved yield. The surface area and micropore volume of the synthesized materials confirm the high quality of products. The reactor was studied to determine the effect of different synthesis parameters including ligand to metal ratio, base concentration, and mixing intensity. The base concentration has the most effect on the product size, morphology, and yield. The versatility of the reactor is shown by synthesizing ZIF-67 with 79% yield. Further, a larger reactor was constructed and tested, demonstrating that the method can be scaled to increase productivity. Overall, this work presents a versatile and scalable route for nanoparticle synthesis.
