Abstract:

 

The Prussian Blue (PB) nanoparticles can be
obtained by reacting the hexacyanometal center with metal ions in the existence
of polymers such as polyethyleneglycol (PEG). In this study, a pentacyanometal
complex, [Fe(CN)5NO]2-, was used in addition to hexacyanometal
ion, [Fe(CN)6]3-, to obtain nanoparticles coated with
PEG. PB nanoparticles have been prepared, characterized, and comprehensive
electrochemical studies were performed to investigate their performance for
water oxidation electrocatalysis. The effect the ratio of PEG to the morphology
and the water oxidation electrocatalytic performance have also been
interrogated. Overall, the study clearly indicates that Co-FeNO@PEG with 1:10
and 1:25 Co:PEG rate show the best electrocatalytic activity with an overpotential
of 472 and 489 mV for current density of 1 mA cm-1, respectively.
