Abstract
Abstract The electrochemical reduction of O 2 via a two‐electron reaction pathway to H 2 O 2 provides a possibility for replacing the current anthraquinone process, enabling sustainable and decentralized H 2 O 2 production. Here, a nitrogen‐rich few‐layered graphene (N‐FLG) with a tunable nitrogen configuration is developed for electrochemical H 2 O 2 generation. A positive correlation between the content of pyrrolic‐N and the H 2 O 2 selectivity is experimentally observed. The critical role of pyrrolic‐N is elucidated by the variable intermediate adsorption profiles as well as the dependent negative shifts of the pyrrolic‐N peak on X‐ray adsorption near edge structure spectra. By virtue of the optimized N…
