Guoqiang Jian, Lu Liu and Michael R. Zachariah Facile Aerosol Route to Hollow CuO Spheres and its Superior Performance as an Oxidizer in Nanoenergetic Gas Generators Advanced Functional Materials 23
Hollow CuO spheres with nanosized building blocks are fabricated using a “droplet-to-particle” aerosol spray pyrolysis method. The hollow structure is produced by adding sucrose and H2O2 in the precursor solution as gas-blowing agents. The nanoaluminum thermite with hollow CuO as an oxidizer ignites in a very violent manner and significantly outperforms commercial CuO nanoparticles in both pressurization rate and peak pressure.
