Size-dependent plasmonic effects of M and M@SiO2 (M=Au or Ag) deposited on TiO2 in photocatalytic oxidation reactions

[Display omitted] •Sizes of plasmonic Au, Ag, Au@SiO2 and Ag@SiO2 NPs were selectively controlled.•Size-dependent LSPR effects in photocatalytic oxidation reactions were analyzed.•Compared to M NPs, M@SiO2 NPs show quite different size-dependent plasmonic effects.•Ag25@SiO2/TiO2 showes 3.8 times hig...
