We report two ligand-protected Au₄Ru₂ and Au₅Ru₂ nanoclusters with distinct atomic-packing modes and electronic structures, both of which act as ideal model catalysts for identifying the catalytically active sites of catalysts on the nanoclusters. Au₅Ru₂ exhibits superior catalytic performances to Au₄Ru₂ for N-methylation of N-methylaniline to N-methylformanili, which is likely due to the site-cooperation catalysis of Au₅Ru₂.

配体保护的Au4Ru2和Au5Ru2纳米簇：独特的结构及其对位点合作催化的影响。

我们报告两个配体保护的Au ₄ Ru ₂和Au ₅ Ru ₂纳米团簇具有不同的原子堆积模式和电子结构，它们均充当理想的模型催化剂，用于识别纳米团簇上催化剂的催化活性位。Au ₅ Ru ₂对于N-甲基苯胺的N-甲基化为N-甲基甲酰苯胺的催化性能优于Au ₄ Ru ₂，这可能是由于Au ₅ Ru ₂的位点协同催化作用。
