 This paper presents porous zirconia-toughened alumina ceramics functionalized with O at PD slash O at point-core-shell nanoparticles, N-piece, for in-situ monitoring of catalytic reactions using surface-enhanced Raman scattering, SCRS. These N-piece are synthesized by the O-seed mediated method and colloidally deposited onto the open porous ceramic matrix prepared via the polymer-replicant method. The O at point-n-piece show a Raman enhancement factor up to 106, which is significantly higher than that of nonporous samples. In-situ reaction monitoring via SCRS is demonstrated by the point-catalyzed reduction of 4-nitrothiophenol to 4-aminothiophenol, showing high specificity for analysis of reactants and products. This multifunctional material concept featuring ceramic-sugmented SCRS and catalytic activity can be extended beyond real-time, sensitive reaction monitoring towards high-temperature reactions, photothermal catalysis, bioprocessing and sensing, green energy conversion, and related applications.
