Hetero-nanostructures of plasmonic metals and semiconductors have attracted increasing attention in the field of photocatalysis. However, most of the hetero-nanostructured catalysts are randomly arranged and therefore require comprehensive structural design for optimizing their properties. Herein, we report the robust construction of hierarchical hetero-nanostructures where gold (Au) nanorods and molybdenum disulfide (MoS₂) quantum sheets (QSs) are integrated in highly ordered arrays. Such construction is achieved through porous anodic alumina (PAA) template-assisted electrodeposition. The as-fabricated hetero-nanostructures demonstrate exciting electrocatalysis towards hydrogen evolution reaction (HER). Both plasmon-induced hot-electron injection and plasmonic scattering/reabsorption mechanisms are determinative to the enhanced electrocatalytic performances. Notably, broadband photoresponses of HER activity in the visible range are observed, indicating their superiority compared with random systems. Such integrated hetero-nanoelectrodes could provide a powerful platform for conversion and utilization of solar energy, meanwhile would greatly prompt the production and exploration of ordered nanoelectrodes.

等离子体金属和半导体的异质纳米结构在光催化领域引起了越来越多的关注。但是，大多数杂纳米结构催化剂是无规排列的，因此需要进行全面的结构设计以优化其性能。在这里，我们报告了稳健的分层异质纳米结构，其中金（Au）纳米棒和二硫化钼（MoS ₂量子片（QS）集成在高度有序的阵列中。这种构造是通过多孔阳极氧化铝（PAA）模板辅助电沉积实现的。所制造的杂纳米结构显示出对氢析出反应（HER）的激动人心的电催化作用。等离子体激元诱导的热电子注入和等离子体激元散射/重吸收机制均决定于增强的电催化性能。值得注意的是，观察到HER活性的宽带光响应在可见范围内，表明它们与随机系统相比具有优越性。这种集成的异质纳米电极可以为太阳能的转化和利用提供有力的平台，同时将极大地促进有序纳米电极的生产和探索。
