摘要: Abstract One-dimensional ZnO nanostructures with various morphologies including nanotubes, nanobelts, solid fibers, nanochains, and porous nanotubes were created through adjusting the parameters in single-spinneret electrospinning calcination processes. The evolution of morphology depended strongly on viscosity precursor solutions process. Namely, nanotube was fabricated via a two-step process while nanochain fiber using one-step consisted small nanoparticles. Furthermore, nanobelt when much more zinc added to increase solution. A possible mechanism based Kirkendall effect decomposition polyvinyl pyrrolidone proposed explain formation other one-dimensional structures. photocatalytic activity these samples for degradation Rhodamine B under ultraviolet light investigated, nanobelts showed best efficiency. Besides, deposition Au nanoparticle can further enhance performance due ohmic contact.
