Fig. 4: NP-loaded RPE for batch and continuous flow interfacial catalysis.

a Schematic showing the Pd NPs located in the hollow cavities of rings. b Schematic showing the continuous flow catalytic oxidation of benzyl alcohol to benzaldehyde by Pd NP-loaded RPE. PE represents Pickering emulsion. TBHP represents tert-butyl hydroperoxide. c Optical microscopy image of a single Pd NP-loaded emulsion droplet. Left-down: the appearance of Pd-NP loaded PEs. Right-up: a zoomed-in image of the area shown in the white square. d, e TEM images of the emulsion interface of Pd NP-loaded RPE. f–h Cryo-SEM images show the emulsion interface of Pd NP-loaded RPE. i Schematic and cryo-SEM images indicate the location of Pd NPs at the interface of Pd NP-loaded SPE. j, k Comparison of kinetic curves and CE among RPE and SPE for the oxidation of BA in batch reaction. l, m Comparison of kinetic curves and CE for the oxidation of BA in continuous flow catalytic reaction. Scale bars: 20 µm (c), 1 µm (d), 25 nm (e), 50 µm (f), 2 µm (inset in f), 500 nm (g, h, i).
