To realize the direct hydroxylation of benzene to phenol by hydrogen peroxide, an efficient photoactive catalyst system was prepared by the recombination of HPMoVO and UiO-66-NH. The heterpolyacid was uniformly distributed on the UiO-66-NH, and the combination was stable. The composite could effectively photocatalyze the direct hydroxylation of benzene to phenol by HO 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.
为了实现用过氧化氢将苯直接羟基化为苯酚，通过HPMoVO和UiO-66-NH的复合制备了一种高效的光活性催化剂体系。杂多酸均匀分布在UiO-66-NH上，且该组合稳定。该复合材料能够在乙腈和乙酸的混合溶液中通过HO有效地光催化苯直接羟基化为苯酚。在最佳条件下，产率和选择性分别为14.08%和98.8%。经过5次催化循环后，催化剂的性能仍保持良好。因此，所研究的催化剂体系可能应用于苯羟基化为苯酚的领域。
