Title
Electrocatalytic reduction of NO2−: Platinum modified glassy carbon electrode
Abstract

Platinum particles were electrochemically deposited over glassy carbon (GC) to prepare GC-Pt electrodes. The electrocatalytic behaviors of this electrode have been compared with that of an ordinary polycrystalline(OPC) Pt and GC electrode in reducing NO2− at neutral medium. The as prepared GC-Pt electrode reduced NO2−, exhibiting double-peak reduction waves. The reduction performance of this electrode was noticed at least 7.8 times higher than that of an OPC Pt electrode. The sensitivity of the GC-Pt electrode was found to be enhanced by the temperature rise. A consecutive mechanism, NO2− → NO → NH4+, over the as prepared GC-Pt electrode has been investigated.
