“…In addition, various types of catalysts have also been reported for the direct hydroxylation of benzene to phenol with H 2 O 2 as an oxidant. 13–16 However, the shortcomings of the existing catalyst preparation process, such as high cost or low yield, still exist. In addition, a number of studies have shown that no active oxygen species are generated in the reaction system and the yield of phenol is basically zero without the addition of a catalyst under all conditions.…”

The photocatalytic hydroxylation of benzene to phenol is an important reaction for the synthesis of fine chemicals and pharmaceuticals. However, the development of efficient and selective photocatalysts for this reaction remains a challenge. Here, a highly active and selective Fe‐MOF/2D‐montmorillonite (Fe‐MOF/MMT) photocatalyst was prepared via an in‐situ method for the hydroxylation of benzene to phenol under the visible light irradiation. The Fe‐MOF/MMT composite exhibited excellent photocatalytic performance, with phenol yield of 30.3% and benzene selectivity of 96.5% within 4 hours. The high activity and selectivity of the Fe‐MOF/MMT photocatalyst were attributed to the synergistic effect between the Fe‐MOF and MMT, as well as the unique 2D structure of MMT, which facilitated charge separation and transfer. The Fe‐MOF/MMT composite also showed good stability and re‐used without significant decrease of activity. This study demonstrated that the potential of Fe‐MOF/MMT as a highly efficient and selective photocatalyst for the hydroxylation of benzene to phenol and provided an insight into the design of advanced photocatalysts for sustainable chemical synthesis.

The hydroxylation of benzene to phenol in presence of hydrogen peroxide was performed using a new biphasic system consisting of a solid phase, a photocatalytically active monolithic polymer composite, immersed in an aqueous phase in which H2O2 is dissolved. In detail, ZnO photocatalytic particles were embedded into the hydrophobic syndiotactic polystyrene (sPS) polymer. Zinc oxide nanostructures (ZnO NSs) were synthesized by an electrochemical procedure. The surface morphology and structure of ZnO nanoparticles and ZnO‐sPS monolithic aerogel composite (ZnO/sPS) were investigated by scanning electron microscopy, X‐ray diffraction and X‐ray photoelectron spectroscopy analysis. Photocatalytic results evidenced that, under UV irradiation, both ZnO NSs and biphasic system water‐photocatalytic composites had a high benzene oxidative property but with very low phenol yield (<2%) at pH=7. To enhance the phenol selective formation, the pH of aqueous solution surrounding the photocatalytic polymer composite was modified. A phenol yield of about 94% and benzene conversion higher than 99% was obtained in alkaline conditions (pH=11).
