This study investigates the impact of ammonium nitrate on the conductivity of pyrolytic manganese dioxide (MnO2). Pyrolytic manganese dioxide is known for its high conductivity and has applications in various fields, including batteries, supercapacitors, and catalysis. Ammonium nitrate, a commonly used oxidizing agent, is introduced to MnO2 to explore its effect on conductivity. The conductivity of the resulting composite material is measured using impedance spectroscopy and compared with pure pyrolytic MnO2. Results indicate a significant enhancement in conductivity with the addition of ammonium nitrate, attributed to changes in MnO2 morphology and surface properties induced by the presence of the oxidizing agent. This study contributes to the understanding of the conductivity enhancement mechanisms in MnO2-based materials and offers insights for the development of improved conductive materials for various applications.
