摘要：
Gold (Au) nanoplates with an average thickness of similar to 70 nm and several 10 mu m in edge size have been mass synthesized through a solution-phase method. Structural studies demonstrate that the Au nanoplates are single crystals with (111) planes as two basal surfaces. Fragmentation of Au nanoplates is found when temperature is higher than 450 degrees C. Investigations on the thermal stability of Au nanoplates suggest that the melting and breaking start mainly at the (110) bounded edges, while the (111) surfaces of Au nanoplates show high stability. This work is valuable for Au nanostructures applied at elevated temperatures.
