An efficient Ru/OM-Co3O4 catalyst was developed for the hydrodeoxygenation of anisole, showing better catalytic performance compared to a commercial Co3O4 supported Ru catalyst. The high catalytic efficiency of Ru/OM-Co3O4 is attributed to the high dispersion of Ru-0 species, enhanced formation of surface defects, and the unique macroporous framework of the OM-Co3O4 support.
A three-dimensional ordered macroporous Co3O4 (OM-Co3O4) supported Ru catalyst was developed for the efficient hydrodeoxygenation (HDO) of anisole. It is revealed that small-sized Ru nanoparticles evenly distributed over the surface of OM-Co3O4 with large quantities of oxygen vacancies could strongly capture Ru-0 species, thereby resulting in strong Ru-Co3O4 interactions. Compared with commercial Co3O4 supported Ru catalyst, Ru/OM-Co3O4 displays a better catalytic HDO performance, with a high cyclohexane yield of 92.4% at 250 degrees C and 0.5 MPa hydrogen pressure after 5 h on stream. Such a significant efficiency of Ru/OM-Co3O4 is mainly attributed to both high dispersion of Ru-0 species and an enhanced formation of surface defects, as well as the unique macroporous framework of OM-Co3O4 support.
