Abstract Carbon nitrides have emerged as promising supports for catalytically active metals in various chemical reactions. Among these, the selective oxidation of benzene to phenol stands out particularly challenging within industry due its traditionally low yields and complex reaction pathways. In our current investigation, we focused on synthesis ionic carbon nitride fragments via a straightforward alkaline hydrolysis method. These demonstrate remarkable ability stabilize iron cations structure (Frag‐Fe), resulting highly efficient photocatalyst oxidation. Employing hydrogen peroxide oxidant single‐step reaction, achieved an impressive 47 % yield using Frag‐Fe at 12 hours, with negligible production CO 2 byproduct. This compelling outcome underscores effectiveness approach generating nitride‐based photocatalysts exceptional activity C−H Our findings not only contribute advancement catalysis, but also hold significant promise development more sustainable processes future.
