      Abstract A novel hydrogen peroxide sensor was fabricated by the seedmediated growth method. First, polyethyleneimine(PEI) functionalized multiwalled carbon nanotubes(MWNTs)were used as growth scaffold on the glass carbon electrode (GCE). Then, Au nanoparticles were electrodeposited uniformly as seeds. Finally, Pt nanoparticles (PtNPs) grew on Au nanoparticles to form Pt@Au coreshell structure nanocomposite. A new type of electrochemical sensor based on Pt@Au/PEIMWNTs nanocomposites for detection of hydrogen peroxide was developed, and the designed Pt@Au/PEIMWNTs/GCE was characterized by electrochemical methods and field emission scanning electron microscopy (FESEM). The Differential pulse experimental results showed that the modified electrode exhibited excellent electrocatalytic activity towards the reduction of H2O2 with the wide linear range from 9.2×1
