Direct hydroxylation of benzene to phenol is one of the most challenging topics to explore new technology of synthesizing phenol,which is of high atom economy and still being developed. However,inert C—H bond and low selectivity of phenol hinder the development of direct hydroxylation. The key technology lies in the design and preparation of efficient catalyst. Iron-containing catalysts have drawn considerable attention for hydroxylation of benzene to phenol due to its unique structural and catalytic properties. Application of iron-containing complexes,biomimetic catalysts and supported catalysts in direct hydroxylation of benzene are reviewed in this paper. Furthermore,the Fenton mechanism and the biomimetic catalysis mechanism are discussed. The oxide and mineral supported iron catalysts which are easily synthesized with high catalytic activity show great potential in industrial application. The study on catalytic mechanism can guide the design and synthesis of efficient catalysts for direct hydroxylation of benzene.
