Selection by gold: Vibrational spectroscopy in conjunction with first-principle calculations demonstrate that small gold clusters can mediate the selective dissociation of one of the four C−H bonds of methane, and thus represents the first step towards its conversion into higher quality chemicals. The distinct selectivity of these gold clusters originates from their finely balanced electronic structure. Au yellow, C gray, H white.

小金团簇对甲烷的选择性CH键裂解

通过金进行选择：振动光谱结合第一性原理计算表明，小的金团簇可以介导甲烷的四个CH键之一的选择性离解，因此代表了将其转化为更高质量的化学药品的第一步。这些金簇的独特选择性源于它们的精细平衡的电子结构。金黄色，C灰色，H白色。
