Ruthenium-based catalysts were prepared by an environmental benign and economical method via Cacumen Platycladi leaf extract and tested in the liquid phase hydrogenation of maleic anhydride and benzene. The catalysts were characterized by a variety of techniques including BET, TEM, HAADF-STEM-EDX, XRD, XPS, FTIR, and TG. Optimization of the catalytic performance of the biosynthesis ruthenium catalysts in the hydrogenation reactions was done, including both the effect of various preparation parameters (Ru loading, preparation temperature and calcination temperature) and the operation parameters (reaction temperature, hydrogen pressure and reaction time). Furthermore, efforts were also made to probe the stability of catalysts. In a word, the merits of excellent durability, sound productivity and preferable reusability grant the catalysts a promising future in the industrial application.
