以硫酸铁水溶液浸渍活性炭制备了一系列铁基催化剂。将这些催化剂用于过氧化氢氧化苯羟基化制苯酚的反应。用Boehm滴定法和X-光电子能谱（XPS）对催化剂进行了表征。结果表明，铁主要通过与活性炭表面羧基的相互作用而固定在活性炭表面。发现这些负载铁物种对标题反应具有催化活性。在303 K、常压、乙腈为溶剂的条件下，苯的转化率为19.6%，苯酚的收率为17.5%，选择性为89.3%。
A series of Fe-based catalysts were prepared by impregnating activated carbon with the aqueous solution of ferric sulfate. These catalysts were employed to the hydroxylation of benzene to phenol using hydrogen peroxide as the oxidant. Boehm titration and X-photoelectron spectroscopy (XPS) were used to characterize the catalysts. It was found that ferric species were mainly anchored on activated carbon via its interaction with surface carboxylic oxygen group. These supported ferric species was found catalytically active for the titled reaction. A benzene conversion of 19.6%, a phenol yield of 17.5% with a selectivity of 89.3% was obtained under optimized conditions: 303K, atmospheric pressure, and using acetonitrile as the solvent.
