A good route(electrodeposition) for the fabrication of gold nanoparticles(nano-Au) attached on ZnO-MWCNTs films modified glassy carbon electrodes (GCE) was proposed.ZnO-MWCNTs films are favor for functioning as the biomimic membrane to immobilize nano-Au.The catalytic oxidation of hydroxylamine has a better result on the nano-Au/ZnO-MWCNTs/GCE because of the synergistic effect of nano-Au and ZnO-MWCNTs films.Under optimal conditions,hydroxylamine were determined at the nano-Au/ZnO-MWCNTs/GCE by typical ampe...
