| Title: | Fabrication of CuO nanoparticle interlinked microsphere cages by solution method | Authors: | Qi, J Tian, H Li, L Chan, HLW |
Issue Date: | 3-Feb-2007 | Source: | Nanoscale research letters, 3 Feb. 2007, 2:107-111 | Abstract: | Here we report a very simple method to convert conventional CuO powders to nanoparticle interlinked microsphere cages by solution method. CuO is dissolved into aqueous ammonia, and the solution is diluted by alcohol and dip coating onto a glass substrate. Drying at 80 °C, the nanostructures with bunchy nanoparticles of Cu(OH)₂can be formed. After the substrate immerges into the solution and we vaporize the solution, hollow microspheres can be formed onto the substrate. There are three phases in the as-prepared samples, monoclinic tenorite CuO, orthorhombic Cu(OH)₂, and monoclinic carbonatodiamminecopper(II) (Cu(NH₃)₂CO₃). After annealing at 150 °C, the products convert to CuO completely. At annealing temperature above 350 °C, the hollow microspheres became nanoparticle interlinked cages. | Keywords: | CuO Microsphere Narnoparticle |
