Synthesis of Au Nanoparticles Supported on Metal Oxides by PS-PVP block Copolymer Micelle Encapsulation Method |
| 초록 |
Au nanoparticles supported on various metal oxides were prepared from PS-PVP block copolymer micelles. For the synthesis, PS-PVP block copolymer was dissolved in toluene forming inversed micelles, and then HAuCl4.3H2O was added to the solution and stirred for 48hrs allowing AuCl4- to be diffused into the core of the inversed micelles. Several kinds of polymers were used to get different Au sizes. It was concluded that particle size was controlled by the length of the hydrophilic part (PVP). Different metal oxides were added into this gold containing precursors and the solvent was evaporated. The dried products were calcined at various temperatures to figure out the influence calcination temperature on the particles size of Au on metal oxide. |
