Electrochemical Behavior of Stable Cinder/Prussian Blue Analogue and Its Mediated Nitrite Oxidation

One-pot preparation of Au-RGO/PDDA nanocomposites and their application for nitrite sensing

“…The results showed that the oxidation peak potential of nitrite did not change when the pH value was different. The reason is that the oxidation process is caused by the dynamic control, or it is a proton independent catalytic procedure [31]. The influence of pH on peak current is clearly shown in Fig.…”

Carbon paste electrodes in the new millennium

“…(i) Among newly used instrumental techniques for characterisation measurements, one can mention studies on the carbon paste structure with atomic force microscopy (AFM [42]), scanning electrochemical microscopy (SECM [43]), or surface screening with electrochemical impedance spectroscopy (EIS [44]) and spectroelectrochemistry (SEC [45]). …”

Electrocatalytic oxidation of nitrite at an aluminum electrode modified by a chemically deposited palladium pentacyanonitrosylferrate film

“…It is therefore believed that E p is controlled by kinetics (pH-independent slow reaction C) rather than thermodynamics (pH-dependent overall reaction). Similar observations were also noticed on Prussian Blue modified electrodes for nitrite and hydrazine oxidation [48,49]. The pH-independent nature of the catalytic peak current, indeed the yield of the disproportionation reaction (D), may be attributed to the high concentration of initial NO À 3 as supporting electrolyte anion (0.5 M) as well as to the considerable concentration of initial NO À 2 (10 mM).…”
