Scanning electron microscopy unveiled that PCN-224 cubes were anchored onto MXene’s delaminated sheets. This design uniquely integrated three complementary merits, including high photothermal conversion efficiency endowed by MXene, high charge separation enabled by Schottky-junction, and enzyme-mimetic activity through PCN-224 integration.

Herein, pseudo-graphite proportion in amorphous carbon was controlled by the degree of polymerization of the precursor that was determined by the oligomerization reaction rate. The close electrical conductivities of amorphous carbon with an appropriate range of pseudo-graphite proportion provided a guarantee for impedance matching while avoiding the disparate effects of ohmic loss, thus, the synthetic amorphous carbon with a controllable pseudo-graphite proportion can be used to investigate the impact of polarization loss on the dissipation of microwave. The relative lower pseudo-graphite proportion within limits provided abundance of defects, provoking dipole polarization loss to achieve enhancement of microwave attenuation. The synthetic amorphous carbon with an appropriate proportion of pseudo-graphite phase exhibited excellent microwave absorption with an effective absorption bandwidth (EAB) of 6.64 GHz at a thickness of 2.2 mm over the whole Ku band.
