摘要The electrochemical synthesis of hydrogen peroxide (H2O2) based on 2-electron oxygen reduction reaction (ORR), is a particularly promising alternative route for in-situ application. Herein, we prepared the oxidized graphene aerogel supported cubic manganese carbonate composites (GO(x)/MnCO3) with different GO and MnCO3 ratio through a simple co-precipitation/in-situ coating method. The GO(x)/MnCO3 composites, with uniformly wrapping of GO on the surface of MnCO3 cubic, display high conductivity and abundant catalytic sites for 2-electron ORR. The G(0.2)M shows the best ORR catalytic performance, onset potential of 0.635 VRHE, high H2O2 production selectivity and high stability in 3.5% NaCl electrolyte. Based on this, G(0.2)M as oxygen reduction electrocatalyst, has good antibacterial effect at 0.55 VRHE on the stainless-steel. The antibacterial mechanism is mainly due to the electrocatalytic oxygen reaction of H2O2 and the side reaction of center dot OH and O-2(center dot-). This provides an impressive, effective and environmentally friendly electrochemical approach for antibacterial and antifouling applications. (C) 2020 Published by Elsevier Ltd.
