Abstract

Enzyme-mimetic materials such as Fe-containing zeolites are of research interest due to the high selectivity for the one-step selective oxidation of benzene to phenol over the Fe-catalytic active center at room temperature and ambient pressure. This study investigates a Fe-modified Y zeolite catalysts prepared via a sonochemical method for the oxidation of benzene-to-phenol using water as solvent. These catalysts were subjected to a screening and optimization experiment by a response surface methodology (RSM), evaluating their potential for the synthesis of phenol. Achieving the preparation of a catalyst with an increased phenol selectivity from 3 % to ∼91 % and almost 100 % when evaluated at 30 ºC. Various Fe species, including the α-Fe(II) active site, were detected using UV-Vis spectroscopy, FTIR spectroscopy, and magnetic thermal gravimetric analysis (MTGA). Highlighting the potential of sonochemistry for preparing at mild temperatures (<100 ºC) iron-modified zeolite Y catalysts with room temperature catalytic active in water-based systems.

超声化学制备苯转化为苯酚的 Fe-Y 沸石催化剂

由于含铁沸石催化活性中心在室温和环境压力下具有将苯一步选择性氧化为苯酚的高选择性，因此酶模拟材料（如含铁沸石）备受研究关注。本研究通过超声化学方法制备了一种 Fe 改性 Y 沸石催化剂，用于以水为溶剂进行苯对苯酚的氧化反应。通过响应面法（RSM）对这些催化剂进行了筛选和优化实验，以评估其合成苯酚的潜力。制备出的催化剂对苯酚的选择性从 3% 提高到了 91%，在 30 ºC 时几乎达到了 100%。利用紫外可见光谱、傅立叶变换红外光谱和磁热重量分析 (MTGA) 检测了包括 α-Fe(II) 活性位点在内的各种铁物种。凸显了在温和温度（100 ºC）下制备在水基体系中具有室温催化活性的铁改性沸石 Y 催化剂的声化学潜力。
