Cu/ZnOx@UiO-66 synthesized from a double solvent method as an efficient catalyst for CO2 hydrogenation to methanol

The Cu precursor diffused into UiO-66 by the double solvent method is reduced by NaBH₄ to form Cu nanoparticles. After introducing Zn²⁺, Cu/ZnO_x@UiO-66 reduced by H₂ is synthesized, which catalyzes the hydrogenation of CO₂ to methanol efficiently.
