Electrochemical Response of Platinum Ultrathin Layer Formed by Pulsed Laser Deposition

Table 2

Pt active area (𝑆_𝑃𝑡) corresponding to the deposition time calculating by using CVs in 0.5 M sulfuric acid solution as shown in Figure 4.

Sample	𝑆Pt (cm^2)
ULPt(30 s)	0.29
ULPt(60 s)	0.40
ULPt(90 s)	0.88
ULPt(120 s)	1.06
