High yield 1-L scale synthesis of ZIF-8 via a sonochemical route
چکیده انگلیسی

ZIF-8 was prepared using a sonochemical method under pH-adjusted synthesis conditions using NaOH (aq) with a minimal amount of triethylamine. After optimizing the synthesis parameters, it was extended successfully to 1 L-scale synthesis with an 85% product yield at a high substrate concentration (Zn2+:DMF = 1:9.3) in 2 h without compromising the textural properties. The prepared ZIF-8 samples after pelletization demonstrating excellent catalytic activity in the Knoevenagel condensation reaction of benzaldehyde with malononitrile.

ZIF-8 was synthesized with 85% yield in a 1 L vessel using a sonochemical method at high substrate concentration (Zn2+:DMF = 1:9.3) in 2 h after pH control using triethylamine and NaOH solution.Figure optionsDownload as PowerPoint slideHighlights
► Economic and high yield large scale ZIF-8 synthesis using a sonochemical method.
► Process optimization by systematic investigations on synthesis parameters.
► ZIF-8 pellets using a PVA binder tested for the Knoevenagel condensation reaction.
