Iron(III) porphyrin supported on S and N co-doped graphene quantum dot as an efficient photocatalyst for aerobic oxidation of alcohols under visible light irradiation

• Synthesis of Fe(III)tetra(4-sulfonatophenyl)porphyrins (FeTSPP) supported on S and N co-doped graphene quantum dots (S, N: GQDs).
• Noble metal free heterogeneous FeTSPP@S(GQDs), N: GQDs photocatalyst.
• FeTSPP@S, N: GQDs photocatalyst with high selectivity and activity for aerobic oxidation of alcohols under visible light irradiations.
• A recyclable and environmentally-friendly photocatalyst.

In this study, we report the synthesis and impressive performance of Fe(III)tetra(4-sulfonatophenyl)porphyrins (FeTSPP) supported on S and N co-doped graphene quantum dots (S, N: GQDs) as efficient, recyclable, and noble metal free heterogeneous photocatalyst for the selective aerobic oxidation of alcohols to the corresponding carbonyl compounds. It was found that FeTSPP@S, N: GQDs photocatalyst represents a novel chemical function for efficient visible light catalyzed aerobic alcohol oxidation with good conversions and selectivity in water as a green solvent at room temperature. We envision that FeTSPP@S, N: GQDs provide a promising candidate for the development of highly efficient, recyclable, and industrially applicable photocatalyst in fine chemical production with high activity.
