Unveiling the Proton–Electron Transfer Pathway in Zn-Embedded N-Doped Carbon Catalyst for Enhanced CO2 Electroreduction

Proton-electron transfer (PET) processes play a pivotal role in numerous electrochemical reactions; yet, effectively harnessing them remains a formidable challenge. Consequently, unveiling the PET pathway is imperative to elucidate the factors influencing the efficiency and selectivity of small molecule electrochemical conversion. In this study, a Zn-NC model catalyst with N and C vacancies was synthesized using a hydriding method to investigate the universal impact of PET on CO
