Polymers can serve as an effective matrix to stabilize gold nanoparticles. These materials offer a continuous light-activated supply of subnanoclusters, which are composed of few atoms. We report an efficient approach to enhance the catalytic activity of gold subnanoclusters by an in situ feeding of these species thanks to the generation of hot carriers through 5d-6s6p interband transitions on PEG-stabilized Au nanoparticles.

可见光增强 Aun 亚纳米团簇的催化活性：d-sp 带间跃迁的重要性


聚合物可以作为稳定金纳米粒子的有效基质。这些材料提供连续的光激活亚纳米团簇供应，这些亚纳米团簇由很少的原子组成。我们报告了一种通过 PEG 稳定的金纳米粒子上的 5d-6s6p 带间跃迁产生热载流子的原位供给这些物质来增强金亚纳米团簇催化活性的有效方法。
