FeCuCo over aluminum oxide catalyst was prepared to catalytically degrade polystyrene (PS) into ethylbenzene (EB) under mild conditions. This catalyst was characterized by XRD, SEM, STEM-EELS, STEM-EDS, XPS, and physical properties. A significant selectivity toward EB formation at 250 °C was achieved in the absence of hydrogen with 82% liquid yield. End-chain session and cross-linking reactions are proposed to be the dominant pathways in the degradation of PS over FeCuCo to form EB.

Fe-Cu-Co /氧化铝上聚苯乙烯的选择性催化转化为乙苯

制备了在氧化铝催化剂上的FeCuCo以在温和条件下将聚苯乙烯（PS）催化降解为乙苯（EB）。通过XRD，SEM，STEM-EELS，STEM-EDS，XPS和物理性质对该催化剂进行了表征。在不存在氢气的情况下，在250°C时，具有显着的EB形成选择性，液体产率为82％。端链会话和交联反应被认为是PS在FeCuCo上降解形成EB的主要途径。
