A copper-containing polyoxometalate-based metal-organic framework (POMOF), CuCl(trz)[HPWO] (, HENU = Henan University; trz = 1,2,4-triazole), has been successfully synthesized and well-characterized. In addition, the excellent catalytic ability of has been proved by the selective oxidation of diphenylmethane. Under the optimal conditions, the diphenylmethane conversion obtained over is 96%, while the selectivity to benzophenone is 99%, which outperforms most noble-metal-free POM-based catalysts. Moreover, 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.
一种含铜的基于多金属氧酸盐的金属有机框架（POMOF），即CuCl(trz)[HPWO]（，HENU = 河南大学；trz = 1,2,4-三唑），已成功合成并得到充分表征。此外，通过二苯甲烷的选择性氧化证明了其优异的催化能力。在最佳条件下，该催化剂上二苯甲烷的转化率为96%，而对二苯甲酮的选择性为99%，这优于大多数无贵金属的基于POM的催化剂。此外，该催化剂可稳定重复使用五次而活性无明显损失，并且还能以令人满意的转化率和选择性催化不同苄基C-H的氧化，这表明其具有显著的催化活性和可回收性。
