Ordered macroporous Co3O4-supported Ru nanoparticles: A robust catalyst for efficient hydrodeoxygenation of anisole

Spinel-based catalysts for the biomass valorisation of platform moleculesviaoxidative and reductive transformations

“…RuCo-based catalysts were investigated for the HDO of phenolic compounds. [104][105][106] The Ru-loaded macroporous Co 3 O 4 catalyst efficiently converted anisole (∼82% conversion), giving high alkane selectivity (92.4% cyclohexane and 4.2% benzene) under 0.5 MPa H 2 pressure and at 250 °C in 5 h. 104 The catalyst was recyclable for up to five cycles with a negligible drop in anisole conversion. The Ru-decorated Co-based nanocatalyst supported on carbon (with a surface area of 232 m 2 g −1 ) gave an excellent guaiacol conversion, giving ∼94% cyclohexanol yield at 200 °C and 1 MPa H 2 pressure.…”

Hydrogenolysis of Lignin and C–O Linkages Containing Lignin-Related Compounds over a Macroporous Silicalite-1 Array-Supported Ru-Ni Phosphide Composite

“…The use of the highly ordered macroporous array S-1 5 as a support afforded the maximum hydrogenolysis conversion rate and benzene yield of 99.4% and 57.2%, respectively (Table 2, entry 6) and resulted in a minimum yield of oxygen-containing products, including phenol, cyclohexanol, and cyclohexanone. The interconnected macroporous array with pore diameters of ~200 nm promotes mass transport [33][34][35] and acts as a "fishing net" that captures lignin macromolecules in the liquid phase. Subsequently, the captured lignin macromolecules moved into the interior of the macropores and were hydrogenolyzed into smaller molecular products.…”

An efficient bifunctional Ni-Nb2O5 nanocatalysts for the hydrodeoxygenation of anisole

“…Many kinds of catalysts have been researched for CHDO, including precious metals [54,55], transition metal [56][57][58],metal carbide [59], metal phosphates [60] and bifunctional catalysts [53]. Bifunction catalysts contain two types of catalytic active centers: metal center and acid center.…”
