Manganese molybdate nanoflakes on silicon microchannel plates as novel nano energetic material

Nano energetic materials have attracted great attention recently owing to their potential applications for both civilian and military purposes. By introducing silicon microchannel plates (Si-MCPs) three-dimensional (3D)-ordered structures, monocrystalline MnMoO₄ with a size of tens of micrometres and polycrystalline MnMoO₄ nanoflakes are produced on the surface and sidewall of nickel-coated Si-MCP, respectively. The MnMoO₄ crystals ripen controllably forming polycrystalline nanoflakes with lattice fringes of 0.542 nm corresponding to the [Formula: see text] plane on the sidewall. And these MnMoO₄ nanoflakes show apparent thermite performance which is rarely reported and represents MnMoO₄ becoming a new category of energetic materials after nanocrystallization. Additionally, the nanocrystallization mechanism is interpreted by ionic diffusion caused by 3D structure. The results indicate that the Si-MCP is a promising substrate for nanocrystallization of energetic materials such as MnMoO₄.
