“…Three to five datum points were averaged at each pH value with error bars at 1σ . entation, as has been shown previously with related systems [19,33,[45][46][47]. This pH region corresponded to an inflection point at 6.1 for the titration curve of CuChl/Ag solution with H 2 SO 4 (Fig.…”

“…SERS phenomena offer a method of overcoming the critical limitations of Raman spectroscopy (low sensitivity) via a 10 9-15 fold increase in Raman sensitivity [8], [9]. Several strategies have been reported to obtain SERS signals such as immobilization of metal colloids and metal particles on a plate.…”

“…38 However, a mixture of Cu 2 O and Cu 4 O 3 appeared during transient electrodeposition, as indicated by Raman peaks at 625 and 500 cm −1 . 33,35 A hollow site of Cu−O was also detected under both steady and transient conditions, with a shift at 436 cm −1 . 38 Between the 50 Hz and 1 kHz transient electrodeposition, a unique peak of Cu 2 O at 490 cm −1 was observed at the beginning and end of the transient 50 Hz process, while some forms of Cu 2 O at 405 and 450 cm −1 were only present in the 1 kHz transient process.…”

“…The intense peaks at 227 and 273 cm −1 before measurement and at the initial time were confirmed to represent Ag−O stretching vibration and CuO, respectively. 34,35 The Ag−O peak disappeared quickly, while the CuO peak remained during steady electrodeposition. The broad peak at 350−700 cm −1 was decomposed into four to five single peaks.…”
