Data from: 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 the silicon microchannel plates (Si-MCPs) three dimensional (3D) ordered structure, monocrystalline MnMoO4 with a size of tens of micrometers and polycrystalline MnMoO4 nanoflakes are produced on the surface and sidewall of the nickel-coated Si-MCP, respectively. The MnMoO4 crystals ripen controllably forming polycrystalline nanoflakes with the lattice fringes of 0.542 nm corresponding to the (1 ̅11) plane on the sidewall. And these nanoflakes MnMoO4 shows apparent thermite performance which is rarely reported and represents MnMoO4 becomes 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.

纳米含能材料（nano energetic materials）近年来受到广泛关注，因其在民用与军事领域均具备潜在应用价值。通过引入硅微通道板（silicon microchannel plates, Si-MCPs）的三维（3D）有序结构，研究人员在镀镍Si-MCP的表面与侧壁上分别制备出尺寸达数十微米的单晶MnMoO₄与多晶MnMoO₄纳米片。侧壁上的MnMoO₄晶体可受控熟化，形成晶格条纹间距为0.542 nm、对应(1̅11)晶面的多晶纳米片。这类MnMoO₄纳米片展现出罕见报道的显著铝热反应性能，表明MnMoO₄经纳米晶化后可成为一类新型含能材料。此外，本研究通过三维结构引发的离子扩散阐释了其纳米晶化机制。研究结果表明，Si-MCP是一类极具应用前景的衬底，可用于MnMoO₄等含能材料的纳米晶化制备。
