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

Abstract

In this study, we report the synthesis and impressive performance of Fe(III)tetra(4sulfonatophenyl) 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.

Key Green Chemistry research areas from a pharmaceutical manufacturers’ perspective revisited

“…Additionally, the catalysts are typically supported on solid support, nanoparticles 184 or as quantum dotsdoped with the appropriate metal to promote the transformation. 185 While these materials can be somewhat laborious to prepare, the possibility of repeated recovery and reuse minimizes the impact. To date, oxidations of alcohols to aldehydes, ketone and esters has been demonstrated.…”

Strongly coupled CdS/graphene quantum dots nanohybrids for highly efficient photocatalytic hydrogen evolution: Unraveling the essential roles of graphene quantum dots

“…A Z-scheme electron transfer originated from coexistence of p-and ntype conductivity domains in NGO-QDs was proposed to account for the observed photocatalytic activity. In the following studies, GQDs were also used to functionalize the photoactive inorganic and organic materials (semiconductors (SCs) [23][24][25][26][27][28][29][30][31][32][33][34][35][36], polymers [39][40], and dyes [41][42][43][44][45]) for developing advanced nanohybrids with enhanced performances. Specifically, GQDs have been coupled with several SCs including UV-light-responsive TiO2 and ZnO as well as visible-light-responsive CdSe for photo(electro)catalytic applications.…”

“…Accordingly, In 2016, Mahyari et al . devised an active, reusable, and novel heterogeneous photocatalyst for the aerobic oxidation of several alcohols to the related aldehydes . For this purpose, the authors designed and prepared Fe (III)tetra(4‐sulfonatophenyl)porphyrins (FeTSPP) supported on S and N co‐doped graphene quantum dots (S, N: GQDs).…”

“…[37,38] Accordingly, In 2016, Mahyari et al devised an active, reusable, and novel heterogeneous photocatalyst for the aerobic oxidation of several alcohols to the related aldehydes. [39] For this purpose, the authors designed and prepared Fe (III) tetra(4-sulfonatophenyl)porphyrins (FeTSPP) supported on S and N co-doped graphene quantum dots (S, N: GQDs). The results demonstrated that FeTSPP@S, N: GQDs photocatalyst demonstrate a remarkable catalytic activity for the aerobic alcohol oxidation under the visible light ( Figure 5).…”
