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 Ni_1-xCu_x 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.

通过“绿色”超临界抗溶剂 (SAS) 沉淀法制备由具有不同金属比例的 SiO ₂稳定的含 NiCu 催化剂。获得的催化剂通过 X 射线衍射 (XRD)、透射电子显微镜 (TEM) 和 CO 吸附进行表征。将水和硅溶胶添加到前体溶液中使我们能够获得具有 Ni _1-x Cu _x固溶体结构的高负载（金属的 70 重量%）分散金属催化剂，而不会相分离成单个金属。这些多相催化剂用于苯甲醚的加氢脱氧 - 热解液的模型化合物。在制备的催化剂上加氢脱氧过程的主要产物是环己烷。
