Engineering atomically dispersed single Cu–N₃ catalytic sites for highly selective oxidation of benzene to phenol

Abstract

Developing efficient approaches for selective oxidation of arene C–H bonds has been a challenging goal. Here we reported a facile and practical strategy to fabricate the N-doped reduced graphene oxide...

Organic Ionic Liquid Grafted Nano‐CeO2: A Highly Efficient Photocatalyst for Hydroxylation of Benzene and Reduction of Cr (VI)

“…By means of evaporation, the solvent chloroform was removed resulting in a core-shell heterostructure functionalized with an ionic liquid (nano-CeO 2 -IL) (Scheme 1). The interaction of Imidazole and 3-chloropropyltriethoxysilane was confirmed by 1 H NMR spectroscopy as shown in Figure S6. [25,26]…”

“…After the reaction was complete and cooled to room temperature, dichloromethane was used to extract the product (DCM). The synthesized product was further confirmed by 1 H NMR and 13 C NMR spectroscopy (Figure S2 (a, b) ESI)…”

“…One of the most significant reactions in this area is the oxidation of benzene to phenol using photocatalysis. [1][2][3][4][5] Being a pollutant and carcinogen, benzene must be transformed into other useful chemicals to alleviate its harmful effects on the environment. In addition, phenol is a crucial intermediate in the production of various pharmaceuticals, pigments, fibres, plastics, and polymer resins.…”

Single-atom catalysts for catalytic benzene oxidation to phenol: recent progress and future perspectives

“…photocatalytic CO 2 reduction 88 and hydrogen evolution reaction 89,90 ) and heterogeneous reactions (e.g. Fenton-like reactions, hydrogenation of quinolone, and benzene oxidation) 91 with remarkably high catalytic activity and good durability. In recent years, many effective Cu SACs have been developed well for catalytic benzene oxidation reactions, due to the high intrinsic catalytic activity and high natural reserves of the Cu element.…”

Copper-containing POM-based hybrid P2Mo22V4Cu4 nanocluster as heterogeneous catalyst for the light-driven hydroxylation of benzene to phenol

“…Among them, the homogeneous catalyst will be dissolved in the reaction solution and cannot be easily recycled, while the active components of the supported catalysts will inevitably be lost in the reaction. 2,10,[21][22][23][24][25][26] Consequently, the preparation of a favorable and stable photocatalyst for one-step oxidation of benzene to phenol is still a challenging direction. 27 Heteropolyacids are oxygen-containing polyacids whose structure consists of a small number of heteroatoms and polyatoms forming polyhedra {MO X } with oxygen atoms, which are later assembled by co-edge and co-angle forms.…”
