Pd−Al was constructed to deal with the issue that cyclic unsaturated compounds are unstable in hydrogenation reaction. Hydrogenation of 2‐methylfuran as a probe reaction in the fixed‐bed reactor afforded up to 99.9% yield and 100% chemo‐selectivity requiring only 100 °C and 2 MPa pressure. Compared with the previous hydrogenation catalyst, such as Ni based catalyst, Pd−Al nanoalloy catalyst employs better performance. Enhancement of catalytic activity, selectivity and stability was attributed to the construction of nano‐effect and Pd−Al alloy structure with low loading amount of Pd. Furthermore, Pd−Al nanoalloy catalyst presented excellent catalytic stability in hydrogenation reaction running for 150 h. Finally, a feasible mechanism of the reaction was proposed and proved by collecting intermediate.

新型γ-Al2O3负载低浓度Pd纳米合金催化剂提高了2-甲基呋喃的加氢能力

构建Pd-Al是为了解决环状不饱和化合物在氢化反应中不稳定的问题。在固定床反应器中，作为探针反应的2-甲基呋喃的加氢仅需100°C和2 MPa的压力即可提供高达99.9％的产率和100％的化学选择性。与以前的氢化催化剂（例如镍基催化剂）相比，Pd-Al纳米合金催化剂具有更好的性能。催化活性，选择性和稳定性的提高归因于纳米效应的构建和低Pd负载的Pd-Al合金结构。此外，Pd-Al纳米合金催化剂在氢化反应中持续150 h表现出优异的催化稳定性。最后，提出了一种可行的反应机理，并通过收集中间体加以证明。
