Protocol for fabrication and characterization of Fe-SAC@COF for electrocatalytic oxygen evolution reaction

Single-atom catalysts (SACs) have promising atomic utilization efficiency and catalytic activity, but their construction with a specific coordination mode remains challenging. This protocol describes the synthesis of a coordinated Fe-SAC@COF for boosted electrocatalytic oxygen evolution reaction (OER). We also detail the steps for single iron atoms confinement and characterization of the COF and Fe-SAC@COF with X-ray diffraction and transmission electron microscopy technique. For complete details on the use and execution of this protocol, please refer to Wang et al. (2022).
