UiO-66 nanoparticles (NPs) were prepared by the solvothermal method using deep eutectic solvents (DESs) and compared to those prepared using the traditional solvent, dimethylformamide. A mixture of choline chloride:glycerol with a molar ratio of 1:2 was used as a green solvent to prepare the NPs. SEM, a Fourier transform infrared spectrometer, zeta potential, N2 adsorption/desorption, and surface area characterisations were used to characterise the NPs. Results showed that the NPs formed in the DES had a smaller size but the lower surface area and functionalised with new chemical groups due to the DES effect. Also, the modified metal–organic frameworks surface area increased by increasing the incubation time but decreased by increasing the temperature.
