Screen-Printed Electrode Surface Modification with NiCo(2)O(4)/RGO Nanocomposite for Hydroxylamine Detection

We developed a novel hydroxylamine sensor through the surface modification of screen-printed electrode (SPE) with NiCo(2)O(4) nanoparticles/reduced graphene oxide (RGO) nanocomposite (NiCo(2)O(4)/RGO/SPE). We assessed the electrochemical response of hydroxylamine on the as-fabricated sensor, confirm...

description We developed a novel hydroxylamine sensor through the surface modification of screen-printed electrode (SPE) with NiCo(2)O(4) nanoparticles/reduced graphene oxide (RGO) nanocomposite (NiCo(2)O(4)/RGO/SPE). We assessed the electrochemical response of hydroxylamine on the as-fabricated sensor, confirming the high electrocatalytic impact of hydroxylamine oxidation. The electrode produced sensitively responded to hydroxylamine under optimized conditions, with a low limit of detection (2.0 nM) and broad linear dynamic range (0.007–385.0 µM). The presence of NiCo(2)O(4) combined with the modification of RGO resulted in sensitive detection and signal amplification of hydroxylamine oxidation. The proposed sensor was used to determine the existence of hydroxylamine in water samples.
