The Cover Feature shows the size‐dependent reduction temperature of oxidized subnanometer copper clusters supported on hydroxylated alumina. The reduction temperature decreases with cluster size for the supported clusters, in stark contrast with the opposite trend found for free gas‐phase clusters from first principles calculations. These findings underline the importance of cluster–support interactions and show ways of tuning, by size and support effects, the oxidation state of clusters, which can provide a handle to control their catalytic properties.

封面人物：通过支持效应逆转铜簇氧化中尺寸相关的趋势（Eur。J. Inorg。Chem。1/2018）

封面特征显示了负载在羟基氧化铝上的氧化亚纳米铜团簇的还原还原温度，取决于尺寸。还原温度随所支持簇的簇尺寸而降低，这与根据第一性原理计算发现的游离气相簇的相反趋势形成鲜明对比。这些发现强调了簇-载体相互作用的重要性，并显示了通过尺寸和载体效应调节簇的氧化态的方法，这些氧化态可以提供控制其催化性能的方法。可以在S. Vajda，S。Narasimhan等人的来文中找到更多信息。
