Supporting effects of a N-doped carbon film electrode on an electrodeposited Ni@Ni(OH)2 core-shell nanocatalyst in accelerating electrocatalytic oxidation of oligosaccharides

The supporting effect of a N-doped carbon film induced superior crystallinity in electrodeposited Ni@Ni(OH)(2) core-shell nanoparticles. This improvement resulted in a much higher regeneration rate of catalytic sites (NiOOH), leading to higher oxidation currents of sugars. Also, the overpotential of the maltopentaose (G5) oxidation reaction decreased significantly, probably due to the effect of the electrostatic interaction between NPs and G5.

The supporting effect of N-doped carbon film improved the crystallinity of electrodeposited Ni@Ni(OH)(2) core-shell nanoparticles, leading to a higher regeneration rate of catalytic sites and oxidation currents of sugars, as well as a significant decrease in overpotential for the G5 oxidation reaction, possibly due to electrostatic interaction between NPs and G5.
