A new class of gold nanostructures, concave nanocubes, enclosed by 24 high-index {720} facets, have been prepared in a monodisperse fashion by a modified seed-mediated synthetic method. The Cl(-) counterion in the surfactant plays an essential role in controlling the concave morphology of the final product. The concave nanocubes exhibit higher chemical activities compared with low-index {111}-faceted octahedra.
一种新型的金纳米结构，即由 24 个高指数{720}面围成的凹面纳米立方体，通过改进的种子介导合成方法以单分散的方式制备。表面活性剂中的 Cl(-)反离子在控制最终产物的凹面形态方面起着至关重要的作用。与低指数{111}面八面体相比，凹面纳米立方体表现出更高的化学活性。
