Formic Acid Electrooxidation by a Platinum Nanotubule Array Electrode
Figure 6
Chronoamperometry data for the 100 and 200 nm Pt nanotube and the Pt black/10 wt% Nafion catalyst in of 0.25 M HCOOH in 0.5 M H2SO4 at (a) 0.400 and (b) 0.475 V versus SHE. The three plots at each voltage show different time scales to facilitate comparison.
