Exceptional activity of mesoporous β-MnO2 in the catalytic thermal sensitization of ammonium perchlorate

Abstract

Mesoporous β-MnO₂ has been prepared, characterized and demonstrated to possess excellent catalytic activity in the thermal decomposition of ammonium perchlorate. The observed unprecedentedly low decomposition temperatures, fast reaction rates and enhanced heat releases in the catalysed formulations make mesoporous β-MnO₂ promising as a high-performing ballistic modifier in AP-based composite solid rocket propellants.
