Determination of Hydrogen Peroxide Using Electrochemical Sensor Modified with N, P, S Co-Doped Porous Carbon/Chitosan-Nano Copper

Determination of Hydrogen Peroxide Using Electrochemical Sensor Modified with N, P, S Co-Doped... The electrochemical sensor was developed based on electrodeposition of chitosan/copper nanoparticles (CT-nano Cu) on the electrode modified with N, P, S co-doped porous carbon (N, P, S@PC). Scanning electron microscopy image has shown that nano Cu in CT-nano Cu/N, P, S@PC composite is uniform with an average size of about 70 nm. CT-nano Cu/N, P, S@PC modified electrode displays good conductivity. More importantly, the electrochemical sensor based on CT-nano Cu/N, P, S@PC shows good electrocatalytic reduction properties of hydrogen peroxide such as wide linear range, low detection limit, fast response time, high stability and good selectivity, due to the synergistic effect between N, P, S@PC and nano Cu toward H2O2 and the immobilized action of CT as hydrogel. Therefore, this developed sensor based on CT-nano Cu/N, P, S@PC provides a good platform for the detection of H2O2. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Journal of Analytical Chemistry Springer Journals

Abstract

The electrochemical sensor was developed based on electrodeposition of chitosan/copper nanoparticles (CT-nano Cu) on the electrode modified with N, P, S co-doped porous carbon (N, P, S@PC). Scanning electron microscopy image has shown that nano Cu in CT-nano Cu/N, P, S@PC composite is uniform with an average size of about 70 nm. CT-nano Cu/N, P, S@PC modified electrode displays good conductivity. More importantly, the electrochemical sensor based on CT-nano Cu/N, P, S@PC shows good electrocatalytic reduction properties of hydrogen peroxide such as wide linear range, low detection limit, fast response time, high stability and good selectivity, due to the synergistic effect between N, P, S@PC and nano Cu toward H2O2 and the immobilized action of CT as hydrogel. Therefore, this developed sensor based on CT-nano Cu/N, P, S@PC provides a good platform for the detection of H2O2.
