The possibility to apply metal organic framework (MOF) based catalysts for oxidation reaction in gas phase was explored. Catalytic activity of the vanadium oxide catalyst incorporated in MIL-101(Cr) as support was investigated in gas phase ethanol oxidative dehydrogenation (EtOH-ODH) and compared to that of MIL-47(V) metal organic framework material containing vanadium as central metal in the framework structure and to a classical VO_x/ZrO₂ supported vanadium oxide catalyst. It was found that vanadium species, incorporated in MIL-101(Cr) support by a variant of vapor deposition method, are stabilized in the form of well dispersed VO_x species (no vanadium pentoxide clusters was detected in the catalyst). The obtained VO_x@MIL-101(Cr) catalyst exhibited high selectivity towards acetaldehyde (up to 99%) at reaction temperatures not exceeding 200 °C. The catalytic activity of VO_x@MIL-101(Cr) catalyst reached an activity level comparable to that of the classical VO_x/ZrO₂ catalyst, but the specific productivity of acetaldehyde (3 kg_AA kg_cat⁻¹ h⁻¹) was higher by 75% compared with productivity on VO_x/ZrO₂ due to much higher content of vanadium species, which could be hosted by the MOF. On the other hand, MIL-47(V) catalyst exhibited negligible activity seemingly due to coordinatively saturated character of the vanadium centers and/or too high stability of the V^IV oxidation state. This proof-of-concept study proved that application of MOF materials as host matrices for heterogeneous catalysts aiming oxidation reaction in gas phase could be efficient as demonstrated on the example of oxidative dehydrogenation of ethanol.

探索了将基于金属有机骨架（MOF）的催化剂用于气相氧化反应的可能性。在气相乙醇氧化脱氢（EtOH-ODH）中研究了掺入MIL-101（Cr）中作为载体的氧化钒催化剂的催化活性，并将其与以钒为中心金属的MIL-47（V）金属有机骨架材料进行了比较在骨架结构中，并得到经典的VO _x / ZrO ₂负载的钒氧化物催化剂。已发现通过气相沉积方法的一种变体掺入MIL-101（Cr）载体中的钒物质以分散良好的VO _x物质的形式稳定（在催化剂中未检测到五氧化二钒簇）。所得VO _x@ MIL-101（Cr）催化剂在不超过200°C的反应温度下对乙醛具有很高的选择性（高达99％）。VO _x @ MIL-101（Cr）催化剂的催化活性达到了与经典VO _x / ZrO ₂催化剂相当的活性水平，但乙醛的比生产率（3 kg _AA kg kg _cat ^-1  h ^-1）为与VO _x / ZrO _2的生产率相比提高了75％由于钒的含量要高得多，这可能是由财政部托管的。另一方面，MIL-47（V）催化剂表现出的活性微不足道，这似乎是由于钒中心的配位饱和特性和/或^IV氧化态的稳定性太高。该概念验证研究证明，如乙醇氧化脱氢实例所示，将MOF材料用作针对气相氧化反应的非均相催化剂的基质可能是有效的。
