  • Descrição: [Display omitted] •0D-1D-2D assembled Co9S8/CNTs/MoS2 composite is fabricated.•Hybrid structure avoids restacking of MoS2 and agglomeration of Co9S8.•Multidimensional hybrid maximizes synergistic effect of three components.•Composite shows ultrathin, strong, and broadband electromagnetic wave absorption.•Simulation reveals the significant suppression effect on electromagnetic radiation. Rational design of hierarchical structure is essential for preparing high-performance electromagnetic wave (EMW) absorbing materials. Herein, 0D-1D-2D hybridized Co9S8/CNTs/MoS2 composite is prepared by assembling MoS2 nanosheets and Co9S8 particles on metal organic framework compound-derived CNT microcages. This multidimensionally hybridized structure can not only avoid the restacking of MoS2 nanosheets and the agglomeration of Co9S8 particles, but also maximize the synergistic effect of three components. CNT porous microcages with proper conductivity increase conduction loss and promote impedance matching. MoS2 nanosheets assemble into wrinkled surfaces, providing intrinsic polarization loss and increasing EMW scattering area. Randomly distributed Co9S8 particles work as dielectric additives to enhance interfacial polarization effect. Co9S8/CNTs/MoS2 composite exhibits significantly improved EMW absorbing properties in reducing filler loading and broadening absorption bandwidth. At an ultralow filler loading of 9 wt%, the minimum RL value achieves −35.4 dB, and the effective absorption bandwidth boosts to 8.4 GHz. By simulating the electric field distribution and radar scatter section, we further reveal the significant suppression effect of Co9S8/CNTs/MoS2 on electromagnetic scattering radiation.
