However, most COF\u2010based catalysts are limited to two\u2010dimensional (2D) architectures and alkaline conditions, which restrict their practical application. Herein, we report a strategy for constructing three\u2010dimensional (3D) COFs that enable efficient H\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>2<\/jats:sub>\n                    electrosynthesis under neutral conditions. By incorporating phenazine units as linked cores, we achieved a 3D COF with a 6\u2010fold interpenetrated\n                    <jats:italic>dia<\/jats:italic>\n                    topology, where the torsional characteristics of phenazine promote dimensional transformation from 2D to 3D architectures. The resulting BCTA\u2010PZDC\u2010COF exhibits enhanced electronic properties and charge transfer dynamics compared to its benzene\u2010linked counterpart (BCTA\u2010TPTC\u2010COF). The BCTA\u2010PZDC\u2010COF demonstrates exceptional 2e\n                    <jats:sup>\u2212<\/jats:sup>\n                    oxygen reduction reaction (ORR) in neutral electrolyte, achieving 91% H\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>2<\/jats:sub>\n                    selectivity and a mass activity of 4.46\u00a0A g\n                    <jats:sup>\u22121<\/jats:sup>\n                    , representing 68% and 79% improvements over the BCTA\u2010TPTC\u2010COF, respectively. Notably, in a flow cell configuration, the catalyst achieves an H\n                    <jats:sub>2<\/jats:sub>\n                    O\n                    <jats:sub>2<\/jats:sub>\n                    production rate of 6.7\u00a0mol g\n                    <jats:sup>\u22121<\/jats:sup>\n                    h\n                    <jats:sup>\u22121<\/jats:sup>\n                    with a Faradaic efficiency of 90.6%. Theoretical studies indicate that the phenazine structure facilitates optimal adsorption of *OOH intermediates on the catalytic sites, thereby enhancing electrocatalytic performance.
