Abstract Aqueous catalytic phenol has been explored using Pd7P3/SiC catalysts in the presence of H2. Palladium phosphide was prepared by oleoamine reduction and supported on silicon carbide. The physicochemical properties of the catalyst were characterized by inductively Coupled Plasma Emission Spectrometer (ICP-MS), X-ray diffractometer (XRD), transmission electron microscopy (TEM) and X-ray photoelectron spectroscopy (XPS). The results show that palladium phosphide is successfully supported on silicon carbide, and the dispersion is relatively uniform with the particle size is about 6–9 nm. Under the same catalytic conditions, a catalyst with a loading of 2.4 wt% exhibits the best activity. When the temperature is 40 °C, the initial pressure is 5 bar, the conversion of phenol can reach more than 99%, and the selectivity of cyclohexanol reaches 94% after 2 h reaction.

新型高活性、高选择性 Pd7P3/SiC 催化剂上苯酚加氢制环己醇

摘要 已在 H2 存在下使用 Pd7P3/SiC 催化剂探索了水性催化苯酚。磷化钯通过油胺还原制备并负载在碳化硅上。采用电感耦合等离子体发射光谱仪（ICP-MS）、X射线衍射仪（XRD）、透射电子显微镜（TEM）和X射线光电子能谱仪（XPS）对催化剂的理化性质进行了表征。结果表明，磷化钯成功负载在碳化硅上，分散相对均匀，粒径约为6-9 nm。在相同的催化条件下，负载量为 2.4 wt% 的催化剂表现出最好的活性。当温度为40℃，初始压力为5bar时，苯酚的转化率可达99%以上，
