Advanced green approaches for the synthesis of NiCu-containing catalysts for the hydrodeoxygenation of anisole
NiCu-containing catalysts stabilized by SiO2 with a different metals ratio are prepared via the "green" supercritical antisolvent (SAS) precipitation method. Obtained catalysts are characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and CO adsorption. The addition of water and a silica sol into precursor solution allows us to obtain highly loaded (70 wt. % of metals) dispersed metal catalysts with a Ni1-xCux solid solution structure without phase separation into individual metals. These heterogeneous catalysts are used for hydrodeoxygenation of anisole - a model compound of pyrolysis liquid. The main product of the hydrodeoxygenation process over prepared catalysts was cyclohexane.
