Solar light‐assisted rod‐shaped CPTF@FACC photocatalyst: An efficient platform for oxygenation reactions and coenzymes regeneration

Summary Solar light active oxygenation reactions and coenzyme regenerations are play crucial role in the area of pharmaceutical industry. The highly selective and efficient synthesis of oxygen‐containing molecules in an environmental friendly manner is challenging at both industrial and laboratory level. Here, we proposed a new synthetic approach for oxygenation reactions along with coenzyme regenerations using flexible‐activated carbon cloth (FACC) oriented covalent (C) tetrakis(4‐carboxyphenyl) porphyrin (P) and thiourea (T)‐based framework (F), namely, CPTF@FACC photocatalyst. CPTF@FACC exhibits excellent solar light‐harvesting ability, well‐distinct photocatalytic centers, high molar extinction coefficient, excellent charge transport ability, and suitable optical band gap, which make the photocatalyst more efficient for oxygenation (sulfoxidation and epoxidation) reactions along with coenzyme regenerations. The oxygenation reactions were carried out in isopropyl alcohol via in situ production of hydrogen peroxide (H2O2) under solar light using CPTF@FACC photocatalyst with high yields (~97%‐98%). Finally, the CPTF@FACC photocatalyst also show a benchmark example in the coenzymes regeneration with high yields 81.1% and 73.1% for NADH and NADPH in 2 h, respectively. Highly efficient and sustainable CPTF@FACC photocatalyst gives good yield and selectivity in photocatalytic oxygenation reactions under solar light. Greener CPTF@FACC photocatalyst also regenerates 81.1 % and 73.1% of 1,4‐NADH and 1,4‐NADPH coenzyme in 2 hours, respectively.
