Abstract

A novel gallium-based MOF, termed Ga-BPTSC (single crystal) and Ga-BPTP (powder), was synthesized. Structural analysis reveals that Ga-BPTSC and Ga-BPTP are isostructural with a slight difference in the unit cell parameters. Specifically, both Ga-BPTSC and Ga-BPTP are constructed from a trinuclear gallium oxide cluster and BPT3- linker, consisting of a 3D structure with unique micro-channels decorated with small adsorption cavities (similar to 6.5 & Aring;). These structural features enable Ga-BPTP to adsorb a significant amount of toluene and xylenes at trace levels (toluene and xylene uptakes of 6.29 mmol g-1 at P/P0 = 0.005 and similar to 6.1 mmol g-1 at P/P0 = 0.01, respectively). The toluene uptake of Ga-BPTP exceeds that of the recently reported MOFs, ZJU-520 and ZJU-620, as well as benchmark MOFs (e.g. UiO-66 and HKUST-1) at P/P0 = 0.005. Moreover, the breakthrough toluene capture of Ga-BPTP at 200 ppm reveals an uptake of 4.89 mmol g-1, which is considerably higher than that of the benchmark MOFs (e.g. ZIF-8, MIL-100, MIL-101, UiO-66, HKUST-1 and UiO-66-NH2). The development of the Ga-BPT synthetic protocol and its exceptional adsorption and separation capacities pave the way to the discovery and application of a new class of gallium-based MOFs constructed from trinuclear gallium oxide clusters.
