The electron transfer reaction between hexacyanoferrate (III) and sodium borohydride resulted in the formation of hexacyanoferrate (II) ion and dihydrogen borate ion which was strongly catalyzed by AuNPs. The redox reaction is described as BH4- + 8 [Fe (CN)6]3- + 3H2O 8 [Fe(CN)6]4- + H2 BO3- + 8H+ The advantage of hexacyanoferrate ion for this redox study is that both oxidation states of iron (+2 and +3) are quite stable with respect to dissociation and hydrolysis
