Mesoporous Boron-Doped Carbon with Curved BC Active Sites for Highly Efficient HO Electrosynthesis in Neutral Media and Air-Supplied Environments.

Hydrogen peroxide (HO) electrosynthesis via the 2e oxygen reduction reaction (ORR) is considered as a cost-effective and safe alternative to the energy-intensive anthraquinone process. However, in more practical environments, namely, the use of neutral media and air-fed cathode environments, slow ORR kinetics and insufficient oxygen supply pose significant challenges to efficient HO production at high current densities. In this work, mesoporous B-doped carbons with novel curved BC active sites, synthesized via a carbon dioxide (CO) reduction using a pore-former agent, to simultaneously achieve excellent 2e ORR activity and improved mass transfer properties are introduced.
