摘要
Graphitic carbon nitride nanosheets (g-C3N4 NS) were prepared and used for self-templated electrodeposition of copper and copper oxide nanostructures. The as-prepared g-C3N4 NS can provide a lot of anchoring sites for copper ions in the process of electrodeposition. The electrodeposited [email protected] demonstrates high density and good uniformity. During the electrodeposition, the addition of nickel ions had enabled to entrap Ni ions in the lattice of CuO. The CeO2[email protected]/g-C3N4 NS composites have been prepared by the addition of Ce ions in the process of electrodepositing [email protected] onto g-C3N4 NS. The cerium and nickel ions, as the additives, can effectively improve the density and uniformity of the electrodeposited [email protected] Furthermore, the successful entrapment of CeO2 and Ni ions greatly improve electrochemical performance of [email protected]/g-C3N4 NS/ITO in the non-enzymatic detection of glucose. The Ce and Ni ion additives showed a synergistic effect on improving uniformity and density of the electrodeposited [email protected] and electro-catalytic properties of as-prepared composites. The as-prepared [email protected]/g-C3N4 NS/ITO, CeO2[email protected]/g-C3N4 NS/ITO and Ni-doped [email protected]/g-C3N4 NS/ITO have been respectively used for non-enzymatic detection of glucose. These three proposed electrodes all demonstrate good electrochemical performance in the non-enzymatic detection of glucose. The CeO2−[email protected]/g-C3N4 NS/ITO and Ni-doped [email protected]/g-C3N4 NS/ITO appear to greatly improve the electro-catalytic activity toward the oxidation of glucose. Among these three electrodes, the Ni-doped [email protected]/g-C3N4 NS/ITO demonstrated the best electrochemical performance in the detection of glucose. These three proposed electrodes all demonstrated good stability and anti-interference performance.
