Abstract
A facile method for generating Au nanorice enclosed by high-index facets in high purity. The nanorice shows much higher catalytic activity for CO oxidation than multiply twinned particles of Au enclosed by {111} facets at temperatures below 300 °C.
摘要
一种在高纯度下生成由高指数晶面包裹的金纳米稻穗的简易方法。在 300°C 以下的温度下，这种纳米稻穗对 CO 氧化的催化活性明显高于由 {111} 面包裹的多孪晶金颗粒。
