两种不同材料之间晶格应变的存在可用于控制混合胶体纳米结构中的精细结构配置。由此，证明了Au-CdX中Au和CdX从对称构型到不对称构型的相对位置变化，这可以进一步导致等离子体激子耦合的微调和不同的氢光催化性能。这些结果为等离子体增强光催化机制提供了新的见解，并为光还原反应提供了潜在的催化剂。
The existence of lattice strain between two different materials can be used to control the fine structural configuration in a hybrid colloidal nanostructure. Enabled by such, the relative position change of Au and CdX in Au-CdX from a symmetric to an asymmetric configuration is demonstrated, which can further lead to fine tuning of plasmon-exciton coupling and different hydrogen photocatalytic performance. These results provide new insight into plasmon enhanced photocatalytic mechanisms and provide potential catalysts for photoreduction reactions.
