Real time STM observation of Ostwald ripening of Pd nanoparticles on TiO2(110) at elevated temperature
A simple procedure was developed for the preparation of palladium nanoclusters on TiO2 with a bimodal distribution of particle sizes. Scanning tunnelling microscopy was used to observe the evolution of size distribution in real time at high temperatures. The observations were found to be consistent...

| 总结: | A simple procedure was developed for the preparation of palladium nanoclusters on TiO2 with a bimodal distribution of particle sizes. Scanning tunnelling microscopy was used to observe the evolution of size distribution in real time at high temperatures. The observations were found to be consistent with an Ostwald ripening mechanism for cluster growth. |
