A copper-containing polyoxometalate-based metal–organic framework (POMOF), Cu^I₁₂Cl₂(trz)₈[HPW₁₂O₄₀] (HENU-7, HENU = Henan University; trz = 1,2,4-triazole), has been successfully synthesized and well-characterized. In addition, the excellent catalytic ability of HENU-7 has been proved by the selective oxidation of diphenylmethane. Under the optimal conditions, the diphenylmethane conversion obtained over HENU-7 is 96%, while the selectivity to benzophenone is 99%, which outperforms most noble-metal-free POM-based catalysts. Moreover, HENU-7 is stable to reuse for five runs without an obvious loss in activity and also can catalyze the oxidation of different benzylic C–H with satisfactory conversions and selectivities, which implied the significant catalytic activity and recyclability.

含铜的多金属氧酸盐基金属有机骨架作为烷基苯选择性催化氧化的有效催化剂

含铜的多金属氧酸盐金属-有机骨架（POMOF），Cu ^I₁₂ Cl ₂（trz）₈ [HPW ₁₂ O ₄₀ ]（HENU-7，HENU =河南大学； trz = 1,2,4-三唑），已成功合成并具有良好的特性。此外，二苯甲烷的选择性氧化证明了HENU-7的优异催化能力。在最佳条件下，通过HENU-7获得的二苯甲烷转化率为96％，而对二苯甲酮的选择性为99％，优于大多数不含贵金属的POM基催化剂。此外，HENU-7 具有稳定的重复使用能力，可连续运行五次，而活性没有明显损失，并且可以以令人满意的转化率和选择性催化不同苄基CH的氧化，这意味着显着的催化活性和可回收性。
