“…The NiO-PTA/ZIF-8 catalyst and spent NiO-PTA/ZIF-8 catalyst both displayed typical type-IV isotherms with a type H 4 hysteresis loop in the range of P/P 0 = 0.4–0.8, indicating the presence of mesopores 70 . It also displayed high adsorption capacities at high relative pressure (P/P 0 > 0.8), demonstrating the coexistence of macropores and mesopores 71 . These findings indicate that the NiO-PTA/ZIF-8 catalyst possesses hierarchically micro-meso-macroporous textures.…”

Nickel oxide (NiO) and phosphotungstic acid (PTA) supported on a ZIF-8 (NiO-PTA/ZIF-8) catalyst was first synthesized and it showed high activity and good selectivity for the hydrocracking of Jatropha oil. The catalyst was characterized by SEM, SEM-EDS, TEM, N2 adsorption, FT-IR, XRD and XPS. Compared with the NiO-PTA/Al2O3 catalyst, the selectivity of C15-C18 hydrocarbon increased over 36%, and catalytic efficiency increased 10 times over the NiO-PTA/ZIF-8 catalyst. The prepared NiO-PTA/ZIF-8 catalyst was stable for a reaction time of 104 h and the kinetic behavior was also analyzed. This catalyst was found to bypass the presulfurization process, showing promise as an alternative to sulfided catalysts for green diesel production.

“…All characteristics peaks are highly consistent with the simulated pattern of ZIF-8 and published patterns for synthesized ZIF-8 in previous studies. [37,41] The crystallized structure of ZIF-8 was stable after the adsorption by comparing XRD patterns for original and CR loaded ZIF-8. The FTIR spectra proved the boundary surface functional groups on ZIF-8.…”

Dyes exposure in aquatic environment creates risks to human health and biota due to their intrinsic toxic mutagenic and carcinogenic characteristics. In this work, a metal-organic frameworks materials, zeolitic imidazolate framework-8 (ZIF-8), was synthesized through hydrothermal reaction for the adsorptive removal of harmful Congo red (CR) from aqueous solution. Results showed that the maximum adsorption capacity of CR onto ZIF-8 was ultrahigh as 1250 mg g −1. Adsorption behaviors can be successfully fitted by the pseudo-second order kinetic model and the Langmuir isotherm equation. Solution conditions (pH condition and the co-exist anions) may influent the adsorption behaviors. The adsorption performance at various temperatures indicated the process was a spontaneous and endothermic adsorption reaction. The enhanced adsorption capacity was determined due to large surface area of ZIF-8 and the strong interactions between surface groups of ZIF-8 and CR molecules including the electrostatic interaction between external active sites Zn−OH on ZIF-8-and −SO 3 or-N=N-sites in CR molecule, and the π-π interaction.

“…FCC gasoline is one of the important blending components of gasoline products, and more than 90% of sulfur content in a typical refinery gasoline pool comes from FCC gasoline, which means that the deep reduction of sulfur content in FCC gasoline will contribute greatly to the production of ultra clean gasoline [3][4][5]. Hydrotreating is one of the most widely used techniques in refineries for sulfur removal from FCC gasoline.…”
