c4H9OH—c3H7CHO—c3H7COOH+C4H9OHc3H7COOC4H9+H2O Jn 小 根据实验结果,可以得出如下推论:(1)Cu.Ti 催化剂(C7)催化正丁醇脱氢.歧化.酯化 反应的活性 最差,添加 ZnO 后可以大幅提升催化剂反应活性;(2)产物中检测不到正丁酸,这说 明正丁酸可与正丁 醇迅速完成酯化反应;(3)通过物料衡算,在目前实...

The configuration of four (4) systems (C24, C24-Engineered-Ca-encapsulated, Ni-doped, and Ag-decorated) surfaces were optimized to their preferable and stable geometry before going on to the H-adsorption processes and was evaluated using the DFT/TPPSh /GenECP level. The titled surface of int...
2, 3 In nature, N2 can be fixed by microorganisms or events such as lightning.4, 5 Currently, to provide NH3 as a commodity chemical our society heavily relies on the industrial Haber-Bosch process to furnish NH3 from N2 and natural gas at high temperatures and pressures.1 During this ...

The latter is represented by the \( Pm{\bar{3}}m \)–P4mm–Amm2–R3m sequence of BaTiO3, in which each transition is marked by a minimum in the shear modulus [72]. If there is a general conclusion, it might be that coupling of strains between two separate order parameters results...
6131 less positive than (H2O/·OH) (2.27 eV); thus, ·OH cannot be produced. Meanwhile, the LUMO energy of UiO-66 is more negative compared to (O2/·O2−) (−0.33 eV), which means that the photoelectrons at the LUMO of UiO-66 can be cap- tured by dissolved ...
