摘要

具有明确原子结构的金属纳米团簇由于其亚纳米尺寸和可调的有机-无机杂化结构特征，在催化领域具有重要的应用前景。本文中，我们成功地合成了一个11核铜(I)-炔基纳米簇（Cu11），该簇由光敏罗丹明染料分子衍生的炔基配体稳定。值得注意的是，即使在没有介质和贵金属助催化剂的情况下，该Cu11簇也表现出优异的光催化析氢活性（8.13 mmol g−1h−1）。此外，当将Cu11簇加载到TiO2纳米片表面时，所得Cu11@TiO2纳米复合材料的析氢效率显著提高，是纯TiO2纳米片的60倍。Cu11@TiO2中Cu11簇的掺入有效抑制了光生电子和空穴的复合，从而加速了复合材料中电荷的分离和迁移。本研究为设计高活性铜簇基光催化剂提供了新的思路。

Dye-stabilized atomically precise copper clusters for enhanced photocatalytic hydrogen evolution

Metal nanoclusters with well-defined atomic structures offer significant promise in the field of catalysis due to their sub-nanometer size and tunable organic-inorganic hybrid structural features. Herein, we successfully synthesized an 11-core copper(I)-alkynyl nanocluster (Cu₁₁), which is stabilized by alkynyl ligands derived from a photosensitive rhodamine dye molecule. Notably, this Cu₁₁ cluster exhibited excellent photocatalytic hydrogen evolution activity (8.13 mmol g⁻¹h⁻¹) even in the absence of a mediator and noble metal co-catalyst. Furthermore, when Cu₁₁ clusters were loaded onto the surface of TiO₂ nanosheets, the resultant Cu₁₁@TiO₂ nanocomposites exhibited a significant enhancement in hydrogen evolution efficiency, which is 60 times higher than that of pure TiO₂ nanosheets. The incorporation of Cu₁₁ clusters within the Cu₁₁@TiO₂ effectively inhibits the recombination of photogenerated electrons and holes, thereby accelerating the charge separation and migration in the composite material. This work introduces a novel perspective for designing highly active copper cluster-based photocatalysts.
