Electrochemical production of hydrogen peroxide (H2O2) using oxygen reduction (eq. 1) or water oxidation (eq. 2) reactions has emerged as an attractive process for small scale decentralized water treatment in remote areas. O2 + 2(H++e-) ---&gt; H2O2 E0 = 0.70 V (1) 2H2O ---&gt; H2O2 + 2(H++e-) E0 = 1.77 V (2) Since hydrogen peroxide is not the thermodynamically favored product for oxygen reduction and water oxidation reactions, selectivity and activity remain the main challenges for developing catalysts with high efficiency. Over the past years, several efforts have been made to find selective, and active catalysts for these reactions. In this talk, I will summarize our recent efforts in designing suitable catalysts with high selectivity and activity for H2O2 synthesis from both processes.1–7
