“…Pt, Pd, Rh, Ru), a category that comprises the vast majority of commercial supported metal catalysts, by relatively low-intensity visible light, can increase the rate of catalyzed reactions. [27][28][29][30] Illumination of non-plasmonic metal nanostructures can also enable control of reaction selectivity through resonant photoexcitation of bond-specific adsorbate-metal electronic transitions. 31 Despite their promise of light-controlled reaction specificity, the lack of a viable mechanism for effective coupling to the incident light field limits the potential of standalone non-plasmonic catalytic structures for photocatalysis.…”

“…One of the most significant physical properties of nanostructures is their optical/plasmonic properties [13,14], which is characterized by their strong interaction with resonant photons through the excitation of surface plasmon resonance (SPR). The SPR effect can be utilized in the analytical technique of surface enhanced Raman scattering (SERS) [15][16][17][18].…”

“…SiO 2 /Pt/TiO 2 is able to absorb visible light and even near-infrared (NIR) light, which results from Pt optical absorption of scattered light in the near-field of dielectric SiO 2 support [7,8] rather than surface plasmon resonance (SPR) optical absorption of Pt or defects in TiO 2 (see Figure S17-S19 for more details). Whereas,loading Pt NPs onto SiO 2 /TiO 2 by the impregnation method cannot lead to the appearance of distinct absorption peak of Pt NPs in the vis-NIR regions,w hich might be explained by the different spatial distribution of Pt NPs [7] in SiO 2 /TiO 2 /i-Pt from that in SiO 2 /Pt/TiO 2 and SiO 2 /TiO 2 /Pt.
