Nanoporous metals have garnered significant attention in catalysis due to their unique three-dimensional interconnected network structure and pronounced localized surface plasmon resonance (LSPR) properties. In this study, nanoporous Au–Ag shells with varying pore sizes (8, 10, 12, 18 nm) were synthesized, catalytic efficiencies systematically evaluated. The conversion of p-nitrothiophenol (PNTP) dimercapto-azobenzene (DMAB) was used investigate the influence size on reaction kinetics surface-enhanced Raman scattering (SERS) effects. Experimental results reveal that a 12 nm exhibit relatively high efficiency. Furthermore, tuning enables modulation LSPR near-infrared region. These findings highlight critical role determining photocatalytic performance metallic materials provide valuable insights for design optimization highly efficient photocatalysts.
