Here, we combine hexagonally\u2010arranged vertically\u2010aligned silicon nanowire (VA\u2010SiNW) arrays with Au nanoparticles and Au\/Ag nanoshells to study the plasmon\u2010driven dimerization of p\u2010nitrothiophenol (p\u2010NTP) into 4,4\u2032\u2010dimercaptoazobenzene (DMAB). In situ Raman spectroscopy reveals that VA\u2010SiNWs can enhance local electric fields at the metal nanostructures, which we use for SERS and hot electron catalysis. Despite producing the strongest near\u2010field enhancement and the highest SERS response, AuNPs\/SiNW arrays do not deliver the highest reaction rates, indicating that near\u2010field intensity alone does not govern catalytic performance. This discrepancy is attributed to steric hindrance within highly confined hotspots at the Au\/Si interface. Compared with the Au\u2010based substrates, Ag\/SiNW arrays show higher photocatalytic activity, with 532\u00a0nm excitation dramatically accelerating p\u2010NTP photoreduction. Ag\/SiNW arrays also photocatalyze 4\u2010mercaptobenzoic acid decarboxylation, demonstrating their ability to drive oxidation reactions via the generation of reactive oxygen radicals. Overall, our results indicate that VA\u2010SiNW arrays can serve as high\u2010surface\u2010area photonic supports for plasmon\u2010driven chemistry and highlight the critical interplay between field enhancement, hotspot accessibility, and metal choice in optimizing hot electron\u2010induced photocatalytic performance.<\/jats:p>","DOI":"10.1002\/smll.74983","type":"journal-article","created":{"date-parts":[[2026,8,3]],"date-time":"2026-08-03T06:08:04Z","timestamp":1785737284000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Metal\/Si
