“…Although MOFs are frequently isolated as powders, they can also be shaped into several forms to serve a specific application, and are commonly found as granules, monoliths, pellets, thin films, foams, and hollow structures [ 9 ]. MOF films are often employed for several interesting applications, namely, for the production of semiconductors [ 10 ] and sensors [ 11 ], as well as for gas separation and storage [ 12 , 13 ], reaction catalysis [ 14 ], and chromatography [ 15 ].…”

The thermally stable zirconium-based MOF, UiO-66, was employed for the preparation of bonded porous‑layer open‑tubular (PLOT) GC columns. The synthesis included the in situ growth of the UiO-66 film on the inner wall of the capillary through a one-step solvothermal procedure. SEM–EDX analysis revealed the formation of a thin, continuous, uniform, and compact layer of UiO-66 polycrystals on the functionalized inner wall of the column. The average polarity (ΔIav = 700) and the McReynolds constants reflected the polar nature of the UiO-66 stationary phase. Several mixtures of small organic compounds and real samples were used to evaluate the separation performance of the fabricated columns. Linear alkanes from n-pentane to n-decane were baseline separated within 1.35 min. Also, a series of six n-alkylbenzenes (C3–C8) were separated within 3 min with a minimum resolution of 3.09, whereas monohalobenzene mixtures were separated at 220 °C within 14s. UiO-66 PLOT columns are ideally suited for the isothermal separation of chlorobenzene structural isomers at 210 °C within 45 s with Rs ≥ 1.37. The prepared column featured outstanding thermal stability (up to 450 °C) without any observed bleeding or significant impact on its performance. This feature enabled the analysis of various petroleum-based samples.
