Abstract
Owing to the unique mass and heat transfer, fluidic‐ flow control systems or reactors can potentially provide advantages for organic and inorganic syntheses compared to the static reactors. In this study, it is demonstrated that a fluid dynamic reactor based on Taylor– Couette (T– C) flow provides high‐ throughput processes for the exfoliation of hexagonal boron nitride (hBN), syntheses of metal‐ nanoparticle‐ (NP)‐ deposited hBN nanohybrids, and their glycolysis reactions of poly(ethylene terephthalate) (PET). The mechanical shear force and dynamic mixing behavior of the T– C flow lead to a stable colloidal suspension of exfoliated hBN sheets with a high exfoliation yield of 77.9% and high production rate of 0.48 g h− 1. A fast synthesis of metal NPs (Pd, Pt, Ag, and RuO2 NPs) onto the hBN surface is achieved by using the controlled T– C flow within only 2 min owing to the efficient mass and heat transfer of the T– C flow. The T– C flow considerably reduces the reaction time (30 min) and temperature (100 °C) for the Pd/hBN‐ catalyst‐ based glycolysis reaction of PET to bis(2‐ hydroxyethyl) terephthalate compared to those of the conventional static reaction that is performed above 200 °C for 120 min.
