Under the application of oxidation potential, the AuPd@Fe2O3 NPs/GCE exhibits good electrocatalytic activity toward DA, which enables to linearly detect DA in the range of 10 nM–831.61 μM (R2 ...

Fe(III)-(oxyhydr)oxides can exist in at least 15 mineral forms with variable physiochemical properties that span a wide range of formal oxidation-reduction (redox) midpoint potentials (Nealson and ...
