Abstract

The synthesis of zeolitic imidazolate framework-8 (ZIF-8) nanoparticles was investigated using in situ ultrasound monitoring. Particle formation was tracked by measuring ultrasound attenuation and velocity via the pulse-echo method. This noninvasive technique enables the observation of molecular sieve syntheses in both solid and liquid phases with high time-resolution without interfering with the process. The method offers novel insights into the formation mechanism of ZIF-8, including the identification of a crystalline intermediate phase, ZIF-L, prior to the formation of ZIF-8. We show that the ultrasound attenuation is sensitive to the nanoparticle size and can be, thus, used for determination of the particle size in future applications.
