摘要: We present a novel porous Au–Ag alloy particles inlaid AgCl membrane as plasmonic catalytic interfaces with real-time, in situ surface-enhanced Raman spectroscopy (SERS) monitoring. The membranes were obtained via facile two-step, air-exposed, and room-temperature immersion reaction appropriate annealing process. Owing to the designed integration of semiconductor component noble metal particles, both reduction visible-light-driven photocatalytic activities toward organic contaminants attained. Specifically, efficiencies about 94% 4-nitrophenol (4-NP, 5 × 10–5 M) after 8 min reaction, degradation rhodamine 6G (R6G, 12 visible light irradiation demonstrated. Moreover, above 85% conversion 4-NP 4-aminophenol (4-AP) 90% R6G achieved well 6 cycles reactions, by which robust recyclability was confirmed. Further, d...
