Regulatable Phase Manipulation-Enhanced Polarization and Conductance Loss Enabling Hierarchical 3D Microsphere-like MoS with Efficient Microwave Absorption.

Molybdenum disulfide (MoS) has become a new type of microwave absorption (MA) material due to the abundant functional groups and defects, high polarization effect, and controllable structural design. However, the development of MoS has been limited by its inherently low conductance losses and imperfect impedance matching. This study employs ammonium ion (NH) intercalation as a phase manipulation strategy to enhance dielectric loss and form heterogeneous structures by incorporating highly conductive 1T phase into the 2H-MoS crystal phase.
