Abstract Electrochemical sensor based on Prussian blue (PB) and CNT-graphene multilayer electrode was developed for H2O2 determination. CNT-graphene multilayer electrode was prepared by layer-by-layer assembly on ITO-coated glass: alternatively chemical dipping for CNT layer and electrodeposition for graphene layer. PB was deposited on the CNT-graphene multilayer electrode by self assembles technique. The surface morphology of the PB/CNT-graphene modified electrode was characterized by electron scanning microscopy. The PB/CNT-graphene sensor shows high electrochemical activity and excellent stability for H2O2 sensing in a linear dynamic detection range from 0.05 mM ~ 9.5 mM, and its sensitivity was 382.4 μA mM-1 cm-2. It has good selectivity in the presence of electroactive species such as ascorbic acid, dopamine, glucose, and uric acid. Key words: CNT, graphene, hydrogen peroxide, self-assemble
