Heterostructure engineering has emerged as a promising approach for creating high-performance microwave absorption materials in various applications such advanced communications, portable devices, and military fields. However, achieving strong electromagnetic wave attenuation, good impedance matching, low density single heterostructure remains significant challenge. Herein, unique structural design strategy that employs hollow structure coupled with gradient hierarchical heterostructures to achieve is proposed. MoS2 nanosheets are uniformly grown onto the double-layered Ti3C2Tx MXene@rGO microspheres through self-assembly sacrificial template techniques. Notably, heterostructures, comprising matching layer, reduced graphene oxide (rGO) lossy MXene reflective have demonstrated improvements attenuation capabilities. Additionally, incorporation of can further improve while reducing overall composite density. The distinctive enable Ti3C2Tx@rGO@MoS2 exceptional properties. reflection loss value reaches -54.2 dB at thin thickness 1.8 mm, effective bandwidth covers whole Ku-band, up 6.04 GHz. This work provides an exquisite perspective on developing next-generation absorbers.
