英文摘要	direct hydroxylation of benzene to phenol using molecular oxygen is a green route with high atom economy but still a great challenge when compared with the existing method of production. the activation of oxygen is necessary and reductive agents were used to activate dioxygen in a so-called "reductive activation" process. here, nano vanadium oxides that consist mainly of low valence vanadium to activate dioxygen were prepared under different conditions via a hydrothermal method. under the optimized conditions, an excellent phenol selectivity of 96.3% with benzene conversion of 4.2% was achieved over the voc2o4-n-5 without reductive agents. characterizations revealed that voc2o4-n-5 was composed of a mesoporous nanosphere structure with medium strong acid sites and low valence vanadium species. a mechanism was proposed as follows: dioxygen was activated by low valence vanadium in voc2o4-n-5 to produce the active oxygen species which oxidized acetic acid to peracetic acid. then the active oxygen species was subsequently transferred from peracetic acid to benzene and inserted into the c-h bond to give phenol.
