Lattice compression at the ≈1 nm scale was first achieved in a newly synthesized Au₅₂(CHT)₂₈ nanocluster, which exhibits superior electrocatalytic activity for the CO₂ reduction reaction compared to the same-sized Au₅₂(TBBT)₃₂ nanocluster without lattice variation. DFT calculations explain the high CO₂RR performance of the lattice-compressed Au₅₂(CHT)₂₈ and provide a correlation between its structure and catalytic activity, indicating that lattice tuning is an efficient method for tailoring the properties of metal nanoclusters.

约 1 nm 尺度上的晶格压缩

新合成的Au ₅₂ (CHT) ₂₈纳米团簇首次实现了约1 nm尺度的晶格压缩，与相同尺寸且无晶格变化的Au ₅₂ (TBBT) ₃₂纳米团簇相比，该纳米团簇对CO ₂还原反应表现出优异的电催化活性。DFT计算解释了晶格压缩Au ₅₂ (CHT) ₂₈的高CO ₂ RR性能，并提供了其结构和催化活性之间的相关性，表明晶格调节是调整金属纳米团簇性能的有效方法。
