催化应用中非平衡表面生长中纳米团簇和纳米柱的形成：溶液合成中物质扩散传输的生长
Formation of Nanoclusters and Nanopillars in Nonequilibrium Surface Growth for Catalysis Applications: Growth by Diffusional Transport of Matter in Solution Synthesis
摘要：
纳米团簇和纳米柱的生长被认为是在一个模型的表面沉积的积木（原子）从溶液中扩散传输到形成的表面结构。表面重组过程也占在模型中，然后产生感兴趣的催化应用中的形态。利用动力学蒙特卡罗数值方法研究了Pt型金属纳米结构中FCC对称表面特征的出现。可用的结果，如（111）-样的协调，以及建议最佳的生长制度，得到的活性位点的分数与所需的性能进行催化，评价。
英文摘要：
Growth of nanoclusters and nanopillars is considered in a model of surface deposition of building blocks (atoms) diffusionally transported from solution to the forming surface structure. Processes of surface restructuring are also accounted for in the model, which then yields morphologies of interest in catalysis applications. Kinetic Monte Carlo numerical approach is utilized to explore the emergence of FCC-symmetry surface features in Pt-type metal nanostructures. Available results exemplify evaluation of the fraction of the resulting active sites with desirable properties for catalysis, such as (111)-like coordination, as well as suggest optimal growth regimes.
