Thermal Perturbation Nucleation and Controllable Growth of Silver Vanadate Crystals by Dynamic Template Route

Silver vanadate (Ag 4 V 2 O 7 ) nanotube clusters were successfully fabricated by the dynamic template route at room temperature. The sample presented a spherical cluster 8 μm in diameter at the macro level. While in the view of the microcosmic, it showed up with a cluster fabricated from mass nanotubes 1–2 μm in length and 18 nm in internal diameter. Detailed investigations were carried out designed to analyze the control procedure imposed on its reaction condition and heat characteristics. The growth mechanism of Ag 4 V 2 O 7 nanotube clusters has also been elucidated, which indicated that the semipermeable structure of the eggshell membrane and the polymerization of acrylamide played an important role in the formation of Ag 4 V 2 O 7 nanotube clusters. Furthermore, the nanotube clusters exhibited higher photocatalytic properties compared with the traditional Ag 4 V 2 O 7 crystals. The new growth mechanism of the cluster has reference values for the preparation of nanotube structures.
