Abstract

Due to the significance of hydrogen peroxide (H₂O₂) in biological systems and its practical applications, the development of efficient electrochemical H₂O₂ sensors holds a special attraction for researchers. Various materials such as Prussian blue (PB), heme proteins, carbon nanotubes (CNTs) and transition metals have been applied to the construction of H₂O₂ sensors. In this article, the electrocatalytic H₂O₂ determinations are mainly focused on because they can provide a superior sensing performance over non-electrocatalytic ones. The synergetic effect between nanotechnology and electrochemical H₂O₂ determination is also highlighted in various aspects. In addition, some recent progress for in vivo H₂O₂ measurements is also presented. Finally, the future prospects for more efficient H₂O₂ sensing are discussed.
