Hierarchical Growth of Mixed Ammonium Molybdenum\Tungsten Bronze Nanorods

Mixed ammonium molybdenum\tungsten bronzes are available in nanoscopic form via a straightforward solvothermal synthesis in acidic media. The emerging rods exhibit average lengths below 1 m and diameters of 20-30 nm. They self-organize into manifold microscale patterns. The growth of mixed nanorods proceeds within a wide solvothermal parameter window (time, temperature, and pH). Intermediate morphologies give indications of a possible growth mechanism. The complex nanorod arrangements exhibit BET surface areas around 89 m2g-1, and they withstand heating to 450 C.
