An efficient photocatalyst based on H(5)PMo(10)V(2)O(40)/UiO-66-NH(2) for direct hydroxylation of benzene to phenol by H(2)O(2)

To realize the direct hydroxylation of benzene to phenol by hydrogen peroxide, an efficient photoactive catalyst system was prepared by the recombination of H(5)PMo(10)V(2)O(40) and UiO-66-NH(2). The heterpolyacid was uniformly distributed on the UiO-66-NH(2), and the combination was stable. The com...

Descripción
Sumario:To realize the direct hydroxylation of benzene to phenol by hydrogen peroxide, an efficient photoactive catalyst system was prepared by the recombination of H(5)PMo(10)V(2)O(40) and UiO-66-NH(2). The heterpolyacid was uniformly distributed on the UiO-66-NH(2), and the combination was stable. The composite could effectively photocatalyze the direct hydroxylation of benzene to phenol by H(2)O(2) in the mixture solution of acetonitrile and acetic acid. The yield and selectivity were 14.08% and 98.8% under the optimum condition, respectively. The performance of the catalyst still maintained well after 5 catalytic cycles. Hence, the investigated catalyst system might be applied in the field of hydroxylation of benzene to phenol.
