摘要: Abstract A high-performance PdRu bimetallic catalyst supported on mesoporous silica nanoparticles (MSN), PdRu/MSN, was prepared by a facile impregnation–hydrogen reduction method. It found that PdRu/MSN showed 5 times higher activity than of Pd/MSN towards the liquid-phase hydrogenation phenol. The catalysts were characterized comprehensively multiple techniques, X-ray diffraction (XRD), transmission electron microscopy (TEM), photoelectron spectroscopy (XPS), and hydrogen temperature program (TPR). revealed adding Ru could effectively improve Pd dispersion promote electronic interaction between Ru, both which contribute to enhancing catalytic activity.
