A low-temperature solution route to hollow NH₄VO₃ microspheres with controllable shells

摘要

NH₄VO₃ hollow microspheres with controllable shells have been synthesised by the interaction between AgNO₃ and NH₄VO₃ via a facile one-step low-temperature solution-based method. The diameters and surface roughness of NH₄VO₃ hollow spheres can be readily controlled by altering the molar ratios of NH₄VO₃ to AgNO₃. When the molar ratios of NH₄VO₃ to AgNO₃ increase from 6 : 1 to 8 : 1, the diameters of NH₄VO₃ hollow spheres increase from 500-600 to 800-900 nm and the building blocks of the shells are assembled by nanoparticles and nanorods. The introduction of AgNO₃ and H₂O₂ plays an important role in the formation of NH₄VO₃ hollow microspheres.View full textDownload full textKeywordsnanomaterials, nanostructures, NH4VO3 , hollow microspheresRelated var addthis_config = { ui_cobrand: "Taylor & Francis Online", services_compact: "citeulike,netvibes,twitter,technorati,delicious,linkedin,facebook,stumbleupon,digg,google,more", pubid: "ra-4dff56cd6bb1830b" }; Add to shortlist Link Permalink http://dx.doi.org/10.1080/17458080.2010.524665
