New catalysts based on polymeric ionic liquids were synthesized and applied into selective oxidation of benzyl alcohol. Polymeric ionic liquid microspheres (PILM) were prepared by radical polymerization, and then the cations in the imidazole ring were exchanged with the metal anions. After that, the metal anions were reduced to Pd nanoparticles that was supported on the surface of PILM. This metal loading method favored the maximum amount of supported Pd nanoparticles that were uniformly distributed on the surface of PILM. In addition, the introduction of CeO₂ prevented the aggregation of Pd nanoparticles and finally formed PILM/Pd/CeO₂ catalysts with a core-shell structure. The performance of the PILM/Pd/CeO₂ catalysts was evaluated by changing the [K₂CO₃] : [alcohol] molar ratio, reaction temperature and oxygen flow rate in the oxidation reaction of benzyl alcohol. The conversion and selectivity under the optimal reaction conditions reached 48% and 98% respectively The catalysts were effective and reusable after 5 cycles of experiments. In the end, a mechanism underlying the reaction pathway in benzyl alcohol oxidation was put forward.

合成了基于聚合物离子液体的新型催化剂，并将其应用于苯甲醇的选择性氧化。通过自由基聚合制备聚合物离子液体微球（PILM），然后将咪唑环中的阳离子与金属阴离子交换。之后，将金属阴离子还原为负载在PILM表面的Pd纳米颗粒。这种金属加载方法有利于最大量地将负载的Pd纳米颗粒均匀分布在PILM的表面上。另外，CeO ₂的引入阻止了Pd纳米颗粒的聚集，并最终形成了具有核-壳结构的PILM / Pd / CeO ₂催化剂。通过改变[K]来评估PILM / Pd / CeO ₂催化剂的性能。₂ CO ₃ ]：苄醇的氧化反应中的[醇]摩尔比，反应温度和氧气流量。在最佳反应条件下的转化率和选择性分别达到48％和98％。经过5个实验循环，催化剂是有效的和可重复使用的。最后，提出了苯甲醇氧化反应途径的潜在机理。
