Biomimetic Copper Catalysts for the Electrochemical Oxygen Reduction Reaction

Fuel cell electrocatalsis : oxygen reduction on Pt-based nanoparticle catalysts..

The elegance in the operation lies in the absence of greenhouse gas emissions when elean hydrogen is used as fuel (with water as the only product, see figure 1.1 and reaction 1.3),

Still, in a model experiment using electrodes of standard size (6 mm diameter), even at such high concentrations and temperatures the contribution of the Ohmic drop needs to be

Spccific actidties (at 0.9 V vs. RHE) measured with a rotation rate of 1600 rpm and a scan rate of 20 mV/s are also depicted in figure 3.3b, showing an asccnding trcnd as the NP

Further insight into the effects of particle size and annealing on the ORR activity was provided by modcling the nanostructure evolution depending on the size and

Regardless of the temperature range (20 to 60 Q C) or potential limit (which was as high as -1.7 V versus the reversible hydrogen electrode, RHE), the surface did not suffer any

This is true even when we consider the mass activities at 900 mV versus RHE, shown in figure 6.6C. Carbon supported nanoparticles usually have high mass activities, because one of

The smoothening of the particles into nanotubes is expected to lower the surface area, which it does, but not by a large margin. The decrease in total electrochemical.. The
