摘要
预先合成出纳米粒子Pd@Pt和Pt,再将其负载到金属有机骨架UiO-66上,制备出负载型催化剂Pd@Pt/UiO-66和Pt/UiO-66。利用红外光谱(FT-IR)、紫外可见光谱(UV-Vis)、X射线衍射仪(XRD)、扫描电子显微镜(SEM)、透射电子显微镜(TEM)、比表面积及孔径分析仪(BET)和热重分析仪(TG)等手段对催化剂进行了表征,并对其在不同条件下的CO_(2)加氢催化效率进行了系统研究。结果表明:制备的负载型催化剂Pd@Pt/UiO-66和Pt/UiO-66具有优异的催化性能和长效稳定性。
Nanoparticles Pd@Pt and Pt were synthesized in advance,and then embedded on the metal-organic framework UiO-66 to prepare catalysts Pd@Pt/UiO-66 and Pt/UiO-66.Utilized infrared spectrum(FT-IR),ultraviolet visible spectrum(UV),X-ray diffractometer(XRD),scanning electron microscope(SEM),transmission electron microscope(TEM),specific surface area and aperture analyzer(BET)and thermogravimetric analyzer(TG)characterized the catalysts,and systematically studied catalytic efficiency for CO_(2) hydrogenation under different conditions.The results shown that Pd@Pt/UiO-66 and Pt/UiO-66 had excellent catalytic performance and long-term stability.
