Abstract Selective traditional oxidation of toluene to high‐value products like benzyl alcohol, benzaldehyde, and benzoic acid faces significant challenges due high dissociation energy requirements, harsh reaction conditions, complex product distributions. While photocatalysis using O 2 as an oxidant offers a green alternative, developing efficient durable photocatalysts for selective in both batch flow systems remains challenging. Here, sulfur‐doped polymeric carbon nitride (S‐CN) is demonstrated versatile photocatalyst oxidation, applicable powder form binder‐free panels across various reactor configurations solvents. Tuning S monomer content within supramolecular assemblies that serve S‐CN precursors, allows enhanced light absorption, optimized band positions, specific surface area, tailored structural properties the ensuing catalysts. The achieves selectivity, yielding ∼72% benzaldehyde ∼26% after 24 h. Mechanistic studies confirm concurrent reduction reactions occurring roles · − 1 . Extended time (48 h) enables production (73.4%) with minimal formation (<1%), demonstrating excellent control.
