Gold clusters are considered as widely used catalyst for chemical industry, but the efficiency of catalyst has been limited by the aggregation of the gold atoms, since the active sites are only located on the surface of the catalyst particles. In this paper the surface distribution of gold clusters influenced by spontaneous polarization and temperature is discussed. The morphology of the gold particle on different ferroelectric surface was simulated by the dissipative particle dynamics method, and the results are examined by pulsed laser deposition and Atomic Force Microscopy. The negatively poled surface with temperature adjustment could grow more dispersed gold clusters and offer a new progress to select the ferroelectric materials as the substrates for metal catalyst.

金簇被认为是化学工业中广泛使用的催化剂，但是由于活性位仅位于催化剂颗粒的表面上，因此催化剂的效率受到金原子的聚集的限制。本文讨论了自发极化和温度对金团簇表面分布的影响。用耗散粒子动力学方法模拟了不同铁电表面上金粒子的形貌，并通过脉冲激光沉积和原子力显微镜检查了结果。带有温度调节功能的负极表面可以生长更多分散的金簇，并为选择铁电材料作为金属催化剂的基材提供了新的进展。
