“…In the fingerprint region, several transmittance peaks were observed to identify the functional groups of the ZIF-L. The peaks observed at 420.5, 756.0 and 900–1350 cm −1 are associated with the Zn-N stretching of ZIF-L, the out-of-plane bending of the Hmim ring, and the in-plane bending of the Hmim ring, respectively [ 2 , 29 , 34 , 38 , 40 ].…”

“…In more detail, the in-plane bending of the Hmim ring consists of C-N vibration, C=N vibration, ring stretching, and N-H stretching assigned at 999.1, 1147.6, 1431.1 and 1575.1 cm −1 , respectively [ 2 , 29 , 34 , 38 , 40 ]. Aside from the fingerprint region, two peaks were observed at 3114.8 and 3602.8 cm −1 , which correspond to the aromatic C-H stretching of Hmim and the O-H stretching vibration of adsorbed water [ 2 , 29 , 40 ]. Here, the water as the solvent in the synthesis process is seen by the presence of an O-H stretching vibration peak in this spectrum of ZIF-L.…”

“…There are no unidentified peaks in the spectrum of ZIF-L, and so no impurities affect the ZIF-L structure. A previous study reported the synthesis of ZIFs, especially ZIF-8, with the addition of a modulator, such as acetic acid [ 29 ]. Although the modulator could manage the formation of specific spherical ZIF-8, it gave additional functional groups in the ZIF-8 structure.…”

“…This allows the ZIF-8 to have a rhombic dodecahedron crystal shape [ 1 , 3 , 25 , 27 ]. However, it did not rule out the formation of other crystal shapes, such as hexagonal [ 15 , 28 ], truncated cubic [ 26 ], spherical [ 29 ], rod-like, and cylindrical crystal shapes [ 20 ]. This phenomenon may occur due to differences in the method, parameters and modulator addition.…”

Due to its excellent characteristics, zeolitic imidazole framework-L (ZIF-L) is widely used in various applications, such as drug delivery, wastewater treatments and energy storage. In the synthesis of ZIF-L, the molar ratio of ligand to metal, the reaction time and the temperature are essential parameters to produce excellent ZIF-L. In this work, ZIF-L was synthesized using a facile and green synthesis method. It was statistically investigated and optimized to obtain the best operating conditions. The optimization was carried out toward the amount of adsorbed crystal violet (CV) dye (q) as the response in the statistics. The optimal ZIF-L was obtained using a molar ratio of ligand to metal of 8.2220 for 97 min at 29 °C, where the q value of the CV adsorption onto this optimal ZIF-L reached 823.02 mg/g. The obtained ZIF-L was characterized using SEM, XRD, FTIR and TGA analyses to ensure its excellent characteristics.

“…After the analysis of the SEM image shown in Figure 1A , it can be seen that the particle size of ZIF-8 was relatively uniform, approximately 100 nm. Moreover, the morphology was good and the ZIF-8 nanoparticles had a regular hexahedron shape ( Santoso et al, 2021 ).…”

Ceramics can achieve superlubricity under water lubrication; however, their running-in period is long and application is rather limited by wear limit. Thus, zeolite imidazole ester skeleton (ZIF), an important branch of metal organic framework materials (MOFs), is expected to improve the tribological properties of lubricants and associated additives. As such, it has broad application prospects within the field. In this paper, ZIF-8 nanoparticles of varying concentrations were prepared and linked with amino functional groups. Specimens were used in silicon nitride self-matching pairs and their tribological properties were observed. After the experiment, friction surfaces were analyzed by scanning electron microscope (SEM), energy dispersive spectrometer (EDS), and Fourier transform infrared radiation (FTIR). The experimental results have shown that ZIF-8 nanoparticles greatly reduced both friction and wear. Comprehensively considering running-in time, average COF during the whole process and smooth friction period COF, optimal performance was obtained for the ZIF-8 nanoparticle solution concentration of 1wt%. Furthermore, it was concluded that the lubrication properties of amino-modified ZIF-8 nanoparticles are significantly better compared to that of the unmodified ZIF-8. The anti-friction mechanism of ZIF-8 as a ceramic water lubrication additive was mainly through the filling and forming of nanoparticle film on the ceramic surface.

The chemical/physical properties and reliable performance of nanoporous materials are strongly influenced by the particle size and corresponding distribution. Among many types of MOFs, ZIF‐8, is still widely used and many studies have been conducted to control the particle size and uniformity of ZIF‐8 using surfactants and organic solvents. However, the use of surfactants and organic solvents process is expensive and may cause environmental pollution. For the first time, in this paper, a surfactant‐free, size‐controllable, and scalable green synthesis method of ZIF‐8 particles is reported using four reaction parameters (temperature, concentration, pouring time, and reactant ratio) that affect the formation of nuclei and growth of ZIF‐8 crystals. The as‐synthesized ZIF‐8 nanoparticles show great uniformity and controllable particle sizes in the wide range of 147–915 nm. In addition, a 2 L large‐scale synthesis of ZIF‐8 with narrow size distribution is developed by finely tuned particle size in water without any additives. To demonstrate the efficient utilization of nanopores according to the particle size and size distribution, an adsorption test is conducted on the ZIF‐8 nanoparticles. This study will support the synthesis of size‐controlled ZIF‐8 with narrow size distribution and their composites for achieving high performance in the emerging applications.
