Summary: A spatial confined growth strategy encapsulating small-size MOFs derivatives into hollow carbon nanocages was proposed, showing significant spatial confinement effect on the crystal size and dielectric polarization. The phase hybridization induced by size-dependent oxidation motion led to satisfying microwave attenuation, with optimal reflection loss and effective bandwidth achieved. The strategy offers a versatile methodology for manipulating the size of MOFs derivatives and optimizing dielectric polarization and microwave attenuation.
