Development of a reactor with carbon catalysts for modular .

Abstract. The development of small-scale, decentralized reactors for H 2 O 2 production that can couple to renewable energy sources would be of great benefit, particularly for water purification in the developing world. Herein, we describe our efforts to develop electrochemical reactors for H 2 O 2 generation with high Faradaic efficiencies of >90%, requiring cell voltages of only ~1.6 V.
