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 800-900nm 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.
