Photoelectrochemical Hydrogen Peroxide Production via Simultaneous Reduction and Oxidation Processes

Chemistry – A European Journal, EarlyView.
Hydrogen peroxide (H2O2) is an important chemical substance and also a promising carbon‐free clean fuel. The design of a sophisticated photoelectrochemical (PEC) reaction system enables the solar‐driven H2O2 production through simultaneous water oxidation and oxygen reduction processes (H2O2/H2O2‐PEC cells).
