It is generally believed that the matching of electromagnetic (EM) impedance or making the best of the interface polarization is an efficient way to achieve a good EM wave absorbing capability. Herein, the mixed-dimensional C-MoS2 based magnetic van der Waals heterostructures (vdWHs) were elaborately designed and successfully synthesized through the catalytic decomposition of C2H2 over Fe3O4–MoS2. By controlling the pyrolysis temperature, “3-0-2” type heterostructured C–Fe3O4–MoS2 ternary nanohybrid consisting of three-dimensional (3-D) carbon layers, zero dimensional (0-D) magnetite particles, and two-dimensional (2-D) MoS2 nanosheets (NSs) and “1-0-2” type CNTs-Fe@Fe3C-MoS2 vdWHs consisting of 1-D carbon nanotubes (CNTs), 0-D Fe and Fe3C nanoparticles, and 2-D MoS2 NSs were selectively synthesized. Compared to “0-2” type Fe3O4–MoS2, the obtained results demonstrated clearly that the introduction of carbon to form the mixed-dimensional C-MoS2 based magnetic vdWHs could greatly enhance the EM wave absorpt...
