Honeycomb Carbon Nanofibers: A Superhydrophilic O2‐Entrapping Electrocatalyst Enables Ultrahigh Mass Activity for the Two‐Electron Oxygen Reduction Reaction

Abstract Electrocatalytic two‐electron oxygen reduction has emerged as a promising alternative to the energy‐ and waste‐intensive anthraquinone process for distributed H 2 O 2 production. This process, however, suffers from strong competition from the four‐electron pathway leading to low H 2 O 2 sel... View More
