摘要：采用传统浸渍法与纳米粒子封装法,将聚乙烯吡咯烷酮(PVP)保护的金纳米粒子负载到杂化沸石咪唑酯骨架材料(HZIF)上,通过红外光谱、X射线衍射、扫描电子显微镜和N2物理吸附脱附等手段对负载前后的样品进行了表征,并研究了该催化剂对CO_2氢化反应在不同条件下的催化效率。结果表明:纳米粒子封装法所制备的Au@HZIF材料具有较好的催化性能与稳定性,并具有一定的再生性能。
Polyvinyl pyrrolidone （PVP） protected Au nanoparticles were loaded on hybrid zeolite imidazolate frame- works materials by traditional impregnation and controlled nanoparticle encapsulation method. The as-prepared samples were characterized by FT-IR, XRD, SEM and N2 adsorption-desorption and were employed to explore the catalytic perform ance for CO2 hydrogenation reaction,also the effects of reaction conditions were investigated. The results showed that the Au@ HZIF materials prepared via controlled nanoparticle encapsulation method presented a better catalytic efficiency, with good catalytic stability and regeneration performance.
