To develop a rational fabrication strategy for synthesizing multi-shelled hollow metal-organic frameworks with tunable cavity sizes and shell thicknesses.
Fabricated inhomogeneous chromium (III) terephthalate MOF (MIL-101) crystals via step-by-step crystal growth to establish distinct chemical stability gradients across layers.
Selectively etched the less chemically robust inner layers using acetic acid to generate single-crystalline hollow shells.
Assessed the catalytic performance of the resulting multi-shelled hollow structures during styrene oxidation.
Precise regulation of MOF nucleation and crystallization enabled deliberate control over the cavity dimensions and shell thicknesses of each layer.
Multi-shelled hollow MIL-101 crystals exhibited significantly enhanced catalytic activity in styrene oxidation relative to unetched counterparts.
