Higher reduction potential means

This can be explained by the fact that the Pt precursor has a higher reduction potential than Ni and Rh, which means that Pt 2+ species can be more easily reduced. With a lower amount of Pt 2+ , fewer nuclei were generated during the short nucleation phase, leading to the larger NF size during the growth process [55] .

Higher reduction potential means. The electrons flow from NAD + /NADH couple (−0.320 V) to pyruvate/lactate couple (−0.190 V) because the latter is at higher positive standard reduction potential. This means pyruvate/lactate half reaction goes as shown while the NAD + /NADH couple undergoes oxidation. The NADH is the reducing agent and pyruvate is the oxidizing agent.
