Electrodeposition of Three-dimensional (3D) Ag/Pd Bimetallic Nanodendrites and Application for Total Nitrogen Determination
A novel micro-sensing chip for detecting total nitrogen (TN) was reported,which was based on 3D bimetallic Ag/Pd nanodendrites for electrocatalystic reduction of nitrate.The 3D structured Ag/Pd nanodendrites were synthesized by electrodepositon of Ag and Pd on gold interdigitated microband array electrode (Au-IDA).Such 3D Ag/Pd bimetallic nanodendrites possess an extremely high electrocatalytic activity for nitrate reduction in alkaline media at pH 12.5 hence realizing an excellent performance of TN determination without pH adjusting.The electrochemical detection limit of TN is 0.1mgL-1 and the measurement results of real water samples showed a relative error of less than 10% with UV spectrophotometric method.The present micro-sensing chip has significant potential for developing of portable and inexpensive TN instrument for on-line environmental measurement.
