Fig.2- Cyclic voltammogram far oxidation of COad adsorbed at 50 mV on a chemically platinized Pt electrode in 3 M H2SO4 at 10 mV/s. [Pg.96]

AuNPs were electrodeposited onto a clean gold electrode surface by electrodeposition method. Where, the gold electrode was twice cycled in the potential range + 1.1 V to 0 V in deoxygenated solution containing 0.77 mM HAUCU in 0.5 M H2SO4 at 10 mV s"1 scan rate. This AuNPs modified electrode was then immersed into a 300 pi solution of 0.1 M phosphate buffer (PBS) pH 8, containing 60 pg of AChE for 24 h at 4 °C. Finally this AChE modified... [Pg.296]

Figure 12.4 A series of SFG spectra in the CO stretch region of chemisorbed CO on polycrystalline Pt in a CO-free 0.1 M H2SO4 electrolyte. The atop spectra were fit to (12.5) (see text) to extract the amplitude, frequency, and width [Lu et al., 2005 Lagutchev et al, 2006] (each displayed data point is the average of three or five spectra). The electrode potential was swept at a rate of 5 mV/s, and SFG spectra were obtained every 200 ms. Spectra were obtained at 1 mV intervals, but, to avoid congestion in the plot, averaged spectra are displayed at 10 mV intervals in the pre-oxidation region (V < 0.43 V) and at 3.3 mV intervals in the oxidation region (V > 0.43 V) [Lu et al., 2005].

Figure 12.16 Potential dependent SFG spectra (a) and the Stark tuning plot (b) from chemisorbed CO on Pt nanoparticles in a CO-saturated 0.1 M H2SO4 electrolyte. Each spectrum was acquired for 10 s (forward scan data only are shown). The potential was scanned from — 0.20 to 0.70 V (vs. Ag/AgCl) at 1 mV/s. Pt nanoparticles were of approximately 7 nm size, and were immobilized on an Au disk.
