The Influence of Acetic Acid on the Properties of Microporous Metal–organic Framework MIL-88a at Microfluidic Conditions and room Temperature

This paper presents a new eco-friendly technique for the microfluidic synthesis of metal–organic framework MIL-88a in an aqueous medium at room temperature. Acetic acid as a modulator was used to control the morphology and size of the resulting particles during the synthesis. An increase of acetic acid concentration in a certain range of molar ratios leads to a decrease in the linear size of obtained particles and makes it possible to obtain a material with monodisperse porosity. The synthesized samples were comprehensively characterized by powder X-ray diffraction, Fourier-transform infrared spectroscopy, thermogravimetry, and transmission electron microscopy. The porosity of the obtained materials was calculated according to the BET model, based on the data of low-temperature nitrogen adsorption.
