Controlled synthesis of Co3O4 single-crystalline nanofilms enclosed by (111) facets and their exceptional activity for the catalytic decomposition of ammonium perchlorate

Abstract

Single-crystalline, thermally stable Co₃O₄ (111) nanofilms have been successfully synthesized without any surfactant. The catalytic activity of Co₃O₄ nanofilms was investigated via the thermal decomposition of ammonium perchlorate (AP). AP exhibited unprecedentedly low decomposition temperatures and fast reaction rates in the catalyzed formations, making the Co₃O₄ (111) nanofilms an effective catalyst.
