Published: Aug. 30, 2019

Constructing ordered hierarchical porous structures while maintaining their overall crystalline order is highly desirable but remains an arduous challenge. Herein, we successfully achieve the growth of single-crystalline metal-organic frameworks (MOFs) in three-dimensional (3D) macroporous template voids by a saturated solution-based double-solvent-assisted strategy with precise control over nucleation process. The as-prepared macro-microporous Co-based MOFs (SOM ZIF-67) exhibit structure robust nature. Moreover, SOM ZIF-67 can serve as precursor to derive 3D-ordered cobalt diselenide@carbon (3DOM CoSe2@C) through facile carbonization-selenization treatment. as-derived 3DOM CoSe2@C well preserve precursor. More importantly, CoSe2 nanoparticles could be uniformly confined conductive carbon framework, affording regularly interconnected channels and large surface area. As result, when evaluated cathode material for aluminum-ion batteries, not only effectively facilitate diffusion large-sized chloroaluminate anions also increase contact area electrolyte provide more exposed active sites, thereby exhibiting superior reversible rate capacity (86 mA h g-1 at 5.0 A g-1) remarkable cycling performance (125 after 1000 cycles 2.0 g-1).
