Application


  • Photochromic hydrogels for electronic applications: Ammonium molybdate was utilized in the synthesis of a polyacrylamide/sodium alginate/sodium chloride photochromic hydrogel. This hydrogel exhibits high conductivity, anti-freezing properties, and a fast response, making it suitable for information storage and electronic skin applications (Chen et al., 2024).

  • Microwave absorption materials: The preparation of flower-like carbon nanosheet aggregations embedded with ultrafine Mo(2)C, where ammonium molybdate plays a critical role, offers significant advancements in microwave absorption technology (Wang et al., 2023).
