A combinative effect of two or more individual material properties, such as lattice parameters and chemical properties, has been well-known to generate novel nanomaterials with special crystal growth behavior and physico-chemical performance. This paper reports unusually high catalytic performance of AgPt nanoferns in the hydrogenation reaction of acetone conversion to isopropanol, which is several orders higher compared to the performance shown by pristine Pt nanocatalysts or other metals and metal-metal oxide hybrid catalyst systems. It has been demonstrated that the combinative effect during the bimetallisation of Ag and Pt produced nanostructures with a highly anisotropic morphology, i.e., hierarchical nanofern structures, which provide high-density active sites on the catalyst surface for an efficient catalytic reaction. The extent of the effect of structural growth on the catalytic performance of hierarchical AgPt nanoferns is discussed.

分层双金属AgPt纳米蕨作为选择性丙酮加氢制异丙醇的高性能催化剂。
众所周知，两种或更多种单独的材料特性（例如晶格参数和化学特性）的组合效应可产生具有特殊晶体生长行为和物理化学性能的新型纳米材料。本文报道了在丙酮转化为异丙醇的加氢反应中，AgPt纳米蕨类化合物具有异常高的催化性能，这比原始Pt纳米催化剂或其他金属和金属-金属氧化物杂化催化剂体系所显示的性能高出几个数量级。已经证明，在Ag和Pt的双金属化期间的组合作用产生具有高度各向异性形态的纳米结构，即分级的纳米蕨结构，其在催化剂表面上提供了高密度的活性位点以进行有效的催化反应。
