Highly Selective Synthesis of Phenol from Benzene over a Vanadium‐Doped Graphitic Carbon Nitride Catalyst

Abstract: Design and preparation of efficient and economical catalysts for direct hydroxylation of benzene to phenol is an important topic. In this work, a series of metal‐doped graphitic carbon nitride catalyst (Cu‐, Fe‐, V‐, Co‐, and Ni‐g‐C3N4) were successfully synthesized by using urea as the precursor through a facile and efficient method. The catalysts were characterized systematically using N2 adsorption–desorption, FTIR, thermogravimetric analysis, powder X‐ray diffraction, and X‐ray photoelectron spectroscopy t… Show more

“…With the rising of reaction temperature from 30 to 50˝C, the benzene conversion and phenol yield increases quickly to 16.4% and 15.2%, respectively. This indicates that the rising temperature is beneficial to the hydroxylation reaction because the H 2 O 2 may be decomposed to produce more active species with the increasing temperature [16]. However, when the temperature is increased up to 65˝C, the phenol yield gradually drops to 12.6%, owing to the more drastic self-decomposition of H 2 O 2 and the further oxidation of products at higher temperature [19,23].…”

“…Furthermore, following the increase of catalyst amount from 2.5 to 12.5 mg, the phenol selectivity decreases gradually from 93.5 to 85.2%. In general, the more the amount of catalyst is used, the more vanadium sites may be provided, which is in favor of not only the hydroxylation of benzene to phenol, but also the acceleration of self-decomposition of hydrogen peroxide to oxygen and water [16,20,23]. Thus, the decreased results of catalytic properties could be attributed to the consumption of more hydrogen peroxide over excessive amounts of catalyst.…”

“…A lot of efforts have been made to develop new techniques to solve these drawbacks, direct synthesis of phenol from benzene is preferred. With regard to the low phenol yields and low selectivities to phenol (due to the fact that benzene is hard to be oxidized and phenol is easily suffered from over oxidation) [3], a series of well performed catalysts for hydroxylation of benzene have been designed and synthesized [4][5][6][7][8][9][10][11][12][13][14][15][16][17].…”
