Abstract:
... Electrocatalytic two-electron oxygen reduction reaction (2e⁻ ORR) is a promising strategy to achieve hydrogen peroxide (H₂O₂) production, which can replace the anthraquinone method in industrial processes. Nitrogen-doped carbon materials are active and selective electrocatalysts for 2e⁻ ORR; however, it remains challenging to develop N-doped carbons for practical H₂O₂ production and pinpoint the e ...

Abstract:
... A high efficiency electrochemical energy storage and high areal capacitance solid-state mediator can act as an energy vector to solve the key problem in mixtures of H₂ and O₂ in electrically driven water splitting architectures. It is believed that introducing foreign metal atoms into a monometallic compound could promote the energy storage capacity of the mediator. Herein, based on the theoretica ...
