Ni-Co alloy electrode as a novel electrode has the advantages of high electrocatalytic activity and excellently electrochemical response. Ni-Co alloy electrode is used for preparing electrochemical sensor because of its excellent performance and has attracted considerable attention in recent years. At present, the electrochemical sensors of detecting antibiotics have the disadvantages of high cost, low sensitivity and difficult to discriminate the different antibiotics. In order to improve sensitivity and decrease the cost for detecting antibiotics, this project is aim at the fabrication of a nanoporous electrochemical sensor base on the nano hierarchically porous Pd-HSiO1.5/Ni-Co alloy composite electrode. With this purpose, we propose the fabrication of nano hierarchically porous Pd-HSiO1.5/Ni-Co alloy composite electrode using the method of composite electrodeposition by using nano hierarchically porous Pd-HSiO1.5 particles as the composite particles, the nano hierarchically porous HSiO1.5 particles are prepared by the method of template, and after loading Pd, which recults in the composite electrode with high surface area, high electrocatalytic activity and low cost. In order to discriminate the different antibiotics and detect antibiotics with high sensitivity, the typical characteristics of electrocatalysis of the different antibiotics on the composite electrode are studied by the methods of direct electrochemical analysis and indirect electrochemical analysis. The project will reveal the typical characteristics of electrocatalysis and electrochemical behaviors of the different antibiotics such as Alcohols, esters, amines, sugar and ketones by obtaining their respective electrochemical response signals. Finally realize the recognition of different kinds of antibiotics and high sensitive rapid quantitative detection.
