“…ZIF-8 is called a zeolitic MOF due to its similarity to the tetrahedral framework of zeolites [ 15 ]. 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 ].…”

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.

“…In particular, the large surface areas of 1-D structures and porous morphology are preferred in the design [ 5 , 6 ]. Moreover, composite films with a narrow band gap semiconductor are preferred, which can lead to superior performance of the pure TiO 2 films [ 7 , 8 , 9 ]. Both TiO2 and V 2 O 5 are two important materials due to their excellent electronic, chemical, and optical properties [ 10 , 11 ].…”

Porous V2O5/TiO2 Nanoheterostructure Films with Enhanced Visible-Light Photocatalytic Performance Prepared by the Sparking Method

et al. 2020

Porous V2O5/TiO2 nanoheterostructure films with different atomic ratios of Ti/V (4:1, 2:1, 1:1, and 1:2) were synthesized by a sparking method for the first time. The sparking method, which is a simple and cost-effective process, can synthesize highly porous and composite films in one step. Field-emission scanning electron microscope (FE-SEM) images revealed the porosity morphology of all prepared samples. V2O5/TiO2 nanoheterostructure films were confirmed by Raman spectroscopy, high-resolution transmission electron microscopy (HRTEM), and X-ray photoelectron spectroscopy (XPS). The secondary particle size and band gap of the samples were highly correlated to the V2O5 proportion, resulting in enhanced visible-light absorbance. V2O5/TiO2 nanoheterostructure films at an atomic ratio of 1:1 showed the highest photocatalytic performance, which improved the degradation rate up to 24% compared to pure TiO2 film. It is believed that the formed nanoheterostructure and greater portion of V4+ ions are reflected by this ratio.
