本文报道了强耦合双壳核纳米粒子阵列对析氢反应具有光电催化活性。我们通过自顶向下光刻和基于溶液的化学相结合的方法制备了大面积的Cu-Pt纳米颗粒晶格。这些耦合晶格支持两种不同类型的等离子体模式，局部表面等离子体从个别粒子和表面晶格共振（SLR）从二维晶格，增加HER催化活性在白光照明下高达60%。比较两种等离子体模式在不同波长范围内的光电催化性能，我们发现SLR比局域表面等离子体模式有两倍的活性增强。
This paper reports that strongly coupled bimetallic core–shell nanoparticle arrays show photoelectrocatalytic activity for hydrogen evolution reactions (HER). We fabricated large-area Cu–Pt nanoparticle lattices by combining top-down lithography and solution-based chemistry. These coupled lattices support two different types of plasmon modes, localized surface plasmons from individual particles and surface lattice resonances (SLRs) from the 2D lattice, that increased HER catalytic activity under white-light illumination up to 60%. Comparing photoelectrocatalytic performances of the two plasmon modes at different wavelength ranges, we found that SLRs had two-fold activity enhancement over that from localized surface plasmons.
