A facile strategy to prepare sintering- and leaching-resistant core-shell nanocatalysts is reported. ZIF-derived porous carbon supported Pd nanoparticles are coated with a mesoporous silica shell, preventing Pd nanoparticles from sintering at high temperature and leaching in a catalytic process. This nanocatalyst exhibits excellent catalytic activity and recyclability for the oxidation of benzyl alcohol.
报道了一种制备抗烧结和抗浸出核壳纳米催化剂的简便策略。由沸石咪唑酯骨架材料衍生的多孔碳负载钯纳米颗粒被包覆上一层介孔二氧化硅壳，可防止钯纳米颗粒在高温下烧结以及在催化过程中浸出。这种纳米催化剂对苯甲醇氧化表现出优异的催化活性和可回收性。
