Formic Acid Electrooxidation by a Platinum Nanotubule Array Electrode
Figure 3
Cyclic voltammograms of 100 nm and 200 nm Pt nanotubule electrodes and a Pt black electrode with 10 wt.% Nafion in 0.5 M H2SO4(aq) at 15 mV/s. The highlighted hydrogen adsorption region was used to determine active surface areas, shown in the legend.
