    “…Specifically, by tailoring the GaN nanowires via a simple alkaline-etching step to expose the inner (10 $$\bar{1}\bar{1}$$ 1 ¯ 1 ¯ ) facets, we achieve a highly coupled semiconductor nanowire-cocatalyst heterointerface with strong electron interaction. The strongly coupled reconfigured GaN nanowire/Au heterointerface not only optimizes the electronic structure of Au nanoparticles to form abundant highly active interfacial regions, eventually realizing superior hydrogen evolution activity but also enables GaN nanowires to provide a stronger anchoring effect for Au nanoparticles, preventing the detachment of Au nanoparticles during the intense hydrogen evolution process. …”
