摘要

摘要钯纳米颗粒作为催化剂在化工领域有着广泛的应用。然而，钯的聚集限制了催化效率。本文报道了钯在不同铁电极化表面和温度下的表面聚集动力学。同时，利用耗散粒子动力学方法和密度泛函理论，讨论了减小粒子尺寸以获得分散形貌的方法。在负极表面提供分散的钯形态，温度的影响将在模拟中讨论。

Altering the distribution of Pd nano particles on ferroelectric substrate: Dissipative particle dynamics simulation

Abstract Pd nano particles have been widely used as catalyst in chemical industry. However, the catalytic efficiency has been limited by the Aggregation of the Pd. In this paper, the surface aggregation dynamics of Pd on different ferroelectric polarization surface and temperature were reported. Meanwhile, reducing the particle size to obtain the dispersed morphology of Pd was discussed by the dissipative particle dynamics method and density functional theory. The negatively poled surface offered dispersed Pd morphology, the temperature influence will be discussed in the simulation.

期刊介绍： Ferroelectrics Letters is a separately published section of the international journal Ferroelectrics. Both sections publish theoretical, experimental and applied papers on ferroelectrics and related materials, including ferroelastics, ferroelectric ferromagnetics, electrooptics, piezoelectrics, pyroelectrics, nonlinear dielectrics, polymers and liquid crystals. Ferroelectrics Letters permits the rapid publication of important, quality, short original papers on the theory, synthesis, properties and applications of ferroelectrics and related materials.
