In-situ controllable synthesis of Ag nanoparticles: irradiation induced surface segregation of Ag2V4O11 nanobelt.
Ag2V4O11 nanobelt has been synthesized through a hydrothermal process and its surface segregation leading to the in-situ controllable synthesis of Ag nanoparticles under different irradiation conditions is investigated. The resulted materials are characterized by XRD, TEM, HRTEM, and SAED measurements. It is found that well-distributed Ag nanoparticles with a controlled average diameter in the range of 2-50 nm can be formed in-situ and self-loaded on the surface of Ag2V4O11 nanobelt. The segregation mechanism is also discussed in detail. The silver vanadium salt with self-loaded Ag nanoparticles may find application in catalysis and lithium batteries.
