Improving and Fining of Nanostructures by Mixing W with Mo in Metal Organic Hybrid Crystal

A bialloy-like multilayered bulk single crystal consisting of [(CH3CH2)3NH)]2[W0.25Mo0.75O2(C14H6O4)2] has been synthesized, from which Mo–W-mixed organic hybrid nanotubes with a diameter of about 50 nm and length from tens to hundreds of nanometers were prepared by grinding and ultrasonication. The nanotubes possess the uniformity of Mo-based nanopipes and the rigidity of W-based nanotubules and are more delicate and standardized than W-based nanotubules and shorter than Mo-based nanopipes. Furthermore, the Mo–W-mixed nanotubes are disassembled into Mo-based nanowires with a diameter of about 5 nm and lengths in tens of nanometers and W-based nanoparticles with a diameter of 6 nm, which are much finer than the nanoarchitectures produced from Mo- and W-based crystal isomorphs. This research offers two new methods: one is the improvement of nanostructures in physical properties and morphologies by bialloy-like treatment, and another is the refinement of nanostructures compared with those made from crystal ...
