金属有机骨架材料MIL-53（Al）负载纳米Pd颗粒：一种CO氧化的活性催化剂
Pd Nanoparticles Deposited on Metal-Organic Framework of MIL-53(Al):an Active Catalyst for CO Oxidation
摘要
Abstract
Pd nanoparticles (NPs) supported on a metal-organic framework (MOF), MIL-53(Al) (MIL:Ma-terials of Institut Lavoisier), were prepared using the incipient wetness impregnation method. The struc-tures of the synthesized Pd/MIL-53(Al) catalysts were determined using X-ray diffraction (XRD), transmis-sion electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). The same peaks were ob-served in the XRD patterns of Pd/MIL-53(Al) before and after the catalytic reaction, confirming that the in-tegrity of the MIL-53(Al) support was maintained. The TEM results indicated that the crystal ine porous structure of MIL-53(Al) favored the formation of highly dispersed Pd NPs of average size 2.21 nm. The het-erogeneous catalytic composite materials exhibited high activities for CO oxidation, with ful conversion at 115 °C. The catalytic activity and structure of Pd/MIL-53(Al) were stable after several reaction runs.关键词
