In recent years, metal–organic frameworks (MOFs) have received increasing attention as selective oxidation catalysts and supports for their construction. In this short review paper, we survey recent findings concerning use of MOFs in heterogeneous liquid-phase selective oxidation catalysis with the green oxidant–aqueous hydrogen peroxide. MOFs having outstanding thermal and chemical stability, such as Cr(III)-based MIL-101, Ti(IV)-based MIL-125, Zr(IV)-based UiO-66(67), Zn(II)-based ZIF-8, and some others, will be in the main focus of this work. The effects of the metal nature and MOF structure on catalytic activity and oxidation selectivity are analyzed and the mechanisms of hydrogen peroxide activation are discussed. In some cases, we also make an attempt to analyze relationships between liquid-phase adsorption properties of MOFs and peculiarities of their catalytic performance. Attempts of using MOFs as supports for construction of single-site catalysts through their modification with heterometals will be also addressed in relation to the use of such catalysts for activation of H2O2. Special attention is given to the critical issues of catalyst stability and reusability. The scope and limitations of MOF catalysts in H2O2-based selective oxidation are discussed.

Catalyzed Oxidation

The effect of catalyst on the performance of liquid-phase selective oxidation of cyclohexane as probe reaction over Co-Bi2(MoO4)3 prepared by precipitation method was investigated. The catalyst evaluation results show that the optimum catalyst atomic ratio is n(Mo):n(Bi):n(Co)=1.5:1:0.2 with high selecivity under certain conversion. Meanwhile selective oxidation of Bi2(MoO4)3 was slowed down, selecivity of cyclohexanone and cyclohexanol reached 74.1%, 22.2% respectively.The main composition of the catalyst is Bi2(MoO4)3. Co-Bi2(MoO4)3 had new catalyst sites with Bi3+, Mo6+ and Co2+ having a cooperative effects during oxidation of cyclohexane. Under this condition, selecivity of cyclohexanone improved greatly. Micro-structure and essence disciplinarian of Co-Bi2(MoO4)3 were disclosed by XRD and FTIR. This study could provide experimental data for the technical reform of industry equipment.

Variable Valency

The process of oxidation of hydrocarbon with oxygen proceeds with formation of the corresponding hydroperoxide as the primary product [1,2]. A catalyst is the most important factor that influences on the direction of flow of the oxidation reaction. Catalysts based on metals of variable valency, and their derivatives are the most active in reactions of oxidation of hydrocarbon [3].
