Enhanced electrocatalytic effects of Pd particles immobilized on GC surface on the nitrite oxidation reactions (original) (raw)

In the present paper, nitrite oxidation reaction has been performed using a pristine GC and Pd modified glassy carbon (GC) electrode to investigate catalysis and kinetics of nitrite (NO 2 −) oxidation reactions. The performance of GC electrode increased towards the nitrite oxidation reaction when it achieved catalytic influence from Pd particles. The NOR over the Pd-GC electrode followed by two steps process where the charge transfer steps coupled with the chemical reaction. The nitrite ions involve a single electron transfer reaction NO 2 being the product, which later undergo through a dispropornation reaction yielding NO 2 − and NO 3 − as final products.
