Design, modification, and evaluation of noble metal-free single-atom catalysts for electrochemical H2O2 production. The figure summarizes key aspects of catalyst development, including top-down and bottom-up synthesis strategies, coordination environment modulation at the first and second ligand spheres, and advanced characterization methods for visualizing active sites and reaction pathways. Electrochemical performance is evaluated using rotating ring–disk electrodes and different reactor configurations, such as H-type and flow cells, under acidic, neutral, and alkaline electrolytes. Together, these elements illustrate how catalyst structure, reaction environment, and reactor design collectively govern selective and efficient H2O2 electrosynthesis.
