Tubular catalytic polyHIPE reactor with deposited silver nanoplate nanoparticles

Continuously operating heterogeneous catalytic reactors are an important step towards more efficient and controllable processes compared to batch operation. Ideally, should exhibit high permeability with the catalyst having a surface area volume ratio minimize required amount. An example of such morphology nanoparticles plate-like morphology. In this work, reactor was prepared by depositing silver on positively charged internal phase emulsion monoliths exploiting their negative zeta potential. The nanoplates had edge length 63 nm thickness 13 sphericity factor 0.548. amount deposited silver, determined from absorbance measurement mass difference 12.5 mg/ml remained unaffected concentration groups in range between 69 110 mmol/l, demonstrating robustness proposed approach. unchanged after deposition under flow due polymer microstructure. found be stable various elution conditions, even prolonged reduction 4-nitrophenol. specific activity 428 min−1 g−1, which is order magnitude higher than that cuboctahedra shape one highest reported. approach can applied types variety possible interactions.
