Graphitic carbon nitride (g-C3N4) as a metal-free catalyst for thermal decomposition of ammonium perchlorate

g-C₃N₄ possesses a band gap of approximately 2.7 eV. The conduction-band electrons (e_cb⁻) and valence band holes (h⁺) could be generated when g-C₃N₄ was excited, which accelerate the thermal decomposition of ammonium perchlorate (AP).
